This section helps you change an existing Azure VPN gateway from active-standby to active-active mode, or vice versa using PowerShell. You can also change a gateway in the Azure portal on the Configuration page for your virtual network gateway. Packets destined to the private IP addresses not covered by the previous two routes are dropped. Learn how to configure, create, and manage an Azure VPN gateway. Azure services support ExpressRoute: Microsoft Cloud Platform (Azure, Office 365, and Dynamics 365). Link a DNS private zone to the shared services virtual network. The VPN forwards the client packets to Application Gateway. The local network gateway can be in the same or different location and resource group as the VPN gateway. The new VPN gateways allow multiple sites using policy-based VPNs to connect to the same VPN gateway. You can also deploy other application gateways in the subnet. This is a critical security requirement for most enterprise IT policies. Allow incoming traffic from a source IP or IP range with the destination as the entire Application Gateway subnet address range and destination port as your inbound access port, for example, port 80 for HTTP access. You can only resize a legacy SKU to another supported legacy SKU. You first request the IP address resource, and then refer to it when creating your virtual network gateway. More info about Internet Explorer and Microsoft Edge, Firewall and Application Gateway for virtual networks, Transport layer security (TLS) inspection, Web Application Firewall CRS rule groups and rules, Secure and govern workloads with network level segmentation, Hub-spoke network topology with Azure Virtual WAN. Learn more about configuring forced tunneling. Application Gateway decrypts the packets and searches for threats to web applications. Example: HubRMToClassic. In the Azure portal, navigate to the Hub-RM virtual network, select Peerings, then select + Add. If you advertise the 0.0.0.0/0 route, it might propagate to the Application Gateway subnet. On-premises routes: To the Azure VPN gateway. VPN An important aspect of this configuration is the routing between the on-premises networks and Azure over both the ExpressRoute and VPN paths. But there are some restrictions: You must allow incoming Internet traffic on TCP ports 65503-65534 for the Application Gateway v1 SKU, and TCP ports 65200-65535 for the v2 SKU with the destination subnet as Any and source as GatewayManager service tag. More info about Internet Explorer and Microsoft Edge, Highly Available Cross-Premises and VNet-to-VNet Connectivity, Part 1 - Create and configure your Azure VPN gateway in active-active mode, Part 2 - Establish active-active cross-premises connections, Part 3 - Establish active-active VNet-to-VNet connections, Update an existing VPN gateway from active-standby to active-active, or vice versa, You need to create two Gateway IP configurations with two public IP addresses, You need set the EnableActiveActiveFeature flag. But you can't deploy any other resource in the application gateway subnet. For example, you can't change the SKU from Standard to VpnGw1 (even though VpnGw1 is supported for active-active) because Standard is a legacy SKU and VpnGw1 is a current SKU. If a built-in role doesn't provide the right permission, you can create and assign a custom role for this purpose. Create a routing table with the "Disable BGP route propagation" option, and associate the routing table to the subnets to prevent the route distribution to those subnets. then more specific ranges in the VPN BGP session. For more information on rules and the Open Web Application Security Project (OWASP) Core Rule Set, see. Component roles. Typically, different types of network appliances inspect different aspects of network packets: In some situations, you can combine different types of network security appliances to increase protection. In the example below, if you were peering the two virtual networks named Hub-RM and Spoke-Classic, your account must have the following roles or permissions for each virtual network: Learn more about built-in roles and assigning specific permissions to custom roles (Resource Manager only). For the v1 SKU, user-defined routes (UDRs) are supported on the Application Gateway subnet, as long as they don't alter end-to-end request/response communication. The IP address is dynamically assigned to the resource when the VPN gateway is created. Azure Traffic For this scenario, use NSGs on the Application Gateway subnet. A separate guide, Firewall and Application Gateway for virtual networks, describes design patterns that you can use to arrange the various appliances. You need to set a "default site" among the cross-premises local sites connected to the virtual network. This guide outlines a strategy for implementing zero-trust security for web apps. For example, suppose Application Gateway sends web packets to the IP address 172.16.1.4 and TCP port 443. Each site has the same address space You need to determine which configuration best fits your needs. Provider Tier-0 and Tenant Tier-1 Gateway; Connectivity from Tier-0 (using BGP) to Azure Network via Express Route. The gateway is shown in the diagram below with all addresses: Once the gateway is created, you can use this gateway to establish active-active cross-premises or VNet-to-VNet connection. In this example, the gateway VM with public IP of 40.112.190.5 will use 10.12.255.4 as its BGP Peering Address, and the gateway with 138.91.156.129 will use 10.12.255.5. See How to install and configure Azure PowerShell for more information about installing the PowerShell cmdlets. If you're using Azure Cloud Shell instead of running PowerShell locally, you'll notice that you don't need to run Connect-AzAccount. You can advertise a larger range that encompasses the VPN-connected network over ExpressRoute private peering, then more specific ranges in the VPN BGP session. You can't mix v1 and v2 Azure Application Gateway SKUs on the same subnet. Application Gateway sends the packets to the virtual network gateway. For traffic from on-premises networks to Azure, the Azure prefixes are advertised via both the ExpressRoute private peering BGP, and the VPN BGP. A UDR in the VM subnet redirects the packets to Azure Firewall Premium. Since application gateway resources are deployed within a virtual network resource, Application Gateway performs a check to verify the permission on the provided virtual network resource. Modify a BGP peer. It is possible to change the subnet of an existing Application Gateway within the same virtual network. It is important to make sure that the IP address space of the new virtual network, TestVNet2, does not overlap with any of your VNet ranges. You can set up VNet-to-VNet connections between different subscriptions; please refer to Configure a VNet-to-VNet connection to learn more details. This example so far has configured only one on-premises VPN device, resulting in the diagram shown below: If you have two VPN devices at the same on-premises network, you can achieve dual redundancy by connecting the Azure VPN gateway to the second VPN device. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. New guidance. You can only inject routes into a spoke if the prefix is shorter (less specific) than the virtual network prefix. One network route directly over ExpressRoute without IPsec protection. You should check your Azure role-based access control to verify that users or Service Principals who operate application gateways have at least Microsoft.Network/virtualNetworks/subnets/join/action or some higher permission such as the built-in Network contributor role on the virtual network. If they are the same, you need to change your VNet ASN if your on-premises VPN device already uses the ASN to peer with other BGP neighbors. However, these services require specific network address ranges and firewall ports for enabling the services. Most configurations require a Route-based VPN type. When you use Virtual WAN as a networking platform, two main differences result: You can't link DNS private zones to a virtual hub because Microsoft manages virtual hubs. Creating a gateway can take a while (45 minutes or more to complete, depending on the selected SKU). As we introduce the new VPN gateways, called VpnGw1, VpnGw2, and VpnGw3, we are also updating our deployment guidance. Modify the variables, and then copy and paste into your PowerShell console. It can be difficult to troubleshoot Web Application Firewall alerts. The Application subnet redirects the packets to Azure Firewall Premium. BGP over IKEv2/IPsec: Note (*) Cisco ASA versions 8.4+ add IKEv2 support, can connect to Azure VPN gateway using custom IPsec/IKE policy with "UsePolicyBasedTrafficSelectors" option. Create a route table with a route for 0.0.0.0/0 and a next hop type of. Route Server has the same limitation that Virtual WAN has concerning IP address prefixes. For example, if my subnet address space is 10.5.5.0/24, consider setting the private frontend IP configuration of your gateways starting with 10.5.5.254 and then following with 10.5.5.253, 10.5.5.252, 10.5.5.251, and so forth for future gateways. This applies to non Click Add to complete the BGP peer configuration. If you're running PowerShell locally, sign in. Associate the Route Table to the appropriate subnet. Notice that you must set the gateway object in PowerShell to trigger the actual update. Examples of attacks include SQL code injection and cross-site scripting. See. HTTP Host headers usually don't contain IP addresses. The following diagram illustrates how forced tunneling works. In this case, configure a route table for the Application Gateway subnet. To establish a cross-premises connection, you need to create a Local Network Gateway to represent your on-premises VPN device, and a Connection to connect the Azure VPN gateway with the local network gateway. The instructions below continue from the previous steps listed above. This update can take 30 to 45 minutes, even if you are not resizing your gateway. Enter the Azure VPN gateway subnet using CIDR notation in the Address (IP or DNS) field. Notice that in this step, you must set the gateway object in PowerShell to trigger the actual update. You would also Networks that use Azure Virtual WAN as a platform, Networks that use Azure Route Server to simplify dynamic routing. This update can take up to 30 to 45 minutes. A VPN gateway must have a Public IP address. However, active-active does not support the Standard SKU. Each virtual network can have only In this case, you need 33 IP addresses: 27 for the application gateway instances, one for the private front end, and five for internal use. Routes to the gateway-connected virtual networks or on-premises networks will propagate to the routing tables for the peered virtual networks using gateway transit. Route Server currently requires the device that injects the routes to send them over Border Gateway Protocol (BGP). Be sure to pick a gateway with a Standard Public IP. Template runs as expected in Azure regions with availability zones. If you use the "Try It" Cloud Shell, you will automatically connect to your account. You can configure a Site-to-Site VPN to a virtual network gateway over an ExpressRoute private peering using an RFC 1918 IP address. The old Azure VPN Gateway BGP IP address will no longer exist. The following steps will configure your Azure VPN gateway in active-active modes. In this setup, traffic flows through the active tunnel, and if some issue happens with this tunnel, the traffic switches over to the standby tunnel. This article walks you through the steps to create active-active cross-premises and VNet-to-VNet connections using the Resource Manager deployment model and PowerShell. On the Add peering page, configure the following values: Peering link name: Name the link. This is expected behavior and you can safely ignore these warnings. If you want to resize a current SKU, for example VpnGw1 to VpnGw3, you can do so using this step because the SKUs are in the same SKU family. Find the route table created by AKS in that resource group. Azure Firewall Premium runs security checks: If the packets pass the tests, Azure Firewall Premium takes these steps: Various inspection engines in this architecture ensure traffic integrity: This architecture supports different types of network design, which this article discusses: When checking for malicious traffic, Azure Firewall Premium verifies that the HTTP Host header matches the packet IP address and TCP port. To resize the legacy SKU to one that is supported (in this case, HighPerformance), you simply specify the supported legacy SKU that you want to use. P2S VPN routing behavior is dependent on the client OS, the protocol used for the VPN connection, and how the virtual networks (VNets) are connected to each other. Services such as Azure ExpressRoute, VPN connections, or Azure Virtual WAN deliver the connectivity. You can create more than one VPN connection from your virtual network gateway, typically connecting to multiple on-premises sites. In most systems, Azure Firewall Premium is a shared resource. In this scenario, the traffic first reaches a virtual network gateway in the hub. Your newer VMs and role instances may be running in a VNet created in Resource Manager. Gateway type: Select VPN. This includes learned routes or default 0.0.0.0/0 routes that are propagated by Azure ExpressRoute or VPN gateways in the virtual network. The programming of every virtual network that you connect to the hub then contains these routes. Once your connection is complete, you can add virtual machines to your virtual networks. Azure services support ExpressRoute: Microsoft Cloud Platform (Azure, Office 365, and Dynamics 365). Gateway transit is a peering property that lets one virtual network use the VPN gateway in the peered virtual network for cross-premises or VNet-to-VNet connectivity. The same requirement applies to the traffic from Azure to on-premises networks. A Point-to-Site (P2S) VPN gateway connection lets you create a secure connection to your virtual network from an individual client computer. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The ASNs for the connected VNets must be different to enable BGP and transit routing. The rest of the network flow is the same as the previous case. The configuration files from the previous step contain the gateway configuration settings. Routes with this address that don't point to the internet break the connectivity that Microsoft requires for managing Application Gateway. Associate this route table to the Application Gateway subnet. The following example converts an active-standby gateway into an active-active gateway. Otherwise, you may receive validation errors when running some of the cmdlets. If you're running PowerShell locally, open the PowerShell console with elevated privileges and connect to your Azure account. Logs changes to static routes and BGP events that occur on the gateway: IKEDiagnosticLog: Logs IKE control messages and events on the gateway: P2SDiagnosticLog: Logs point-to-site control messages and events on the gateway. This type of connection is sometimes referred to as a "multi-site" connection. If you don't configure forced tunneling, Internet-bound traffic from your VMs in Azure always traverses from the Azure network infrastructure directly out to the Internet, without the option to allow you to inspect or audit the traffic. More info about Internet Explorer and Microsoft Edge, Connections between different deployment models, in the same or different deployment models. For more information, see. Create the virtual network gateway for TestVNet1. More info about Internet Explorer and Microsoft Edge, virtual network peering constraints and behaviors, Create virtual network peering with the same deployment model, Create virtual network peering with different deployment models, Microsoft.Network/virtualNetworks/virtualNetworkPeerings/write, Microsoft.ClassicNetwork/virtualNetworks/peer. To complete this configuration, verify that you meet the following prerequisites: You have a functioning ExpressRoute circuit that is linked to the VNet where the VPN gateway is (or will be) created. In such scenarios, a UDR can be used to disable BGP route propagation. Select Peerings, then + Add to open Add peering. Select Peerings and select the peering that you want to modify. A well-known CA such as DigiCert or Let's Encrypt typically issues such a certificate. Deploy the servers in a shared services virtual network that you connect to the virtual WAN. If you do require this setting, the default ASN is 65515, although this value can be changed. For more information, see the ExpressRoute Documentation. Once the gateway is created, you will need to obtain the BGP Peer IP address on the Azure VPN Gateway. It can't be configured using the Azure portal. If youre using TLS for point-to-site VPNs on Windows 10 or later clients, you dont need to take any action. Ensure that all management/control plane traffic is sent directly to the Internet and not through a virtual appliance. This lets you establish network topologies that combine cross-premises connectivity with inter-virtual network connectivity. The following procedure helps you create a resource group and a VNet. Although a /24 subnet isn't required per Application Gateway v2 SKU deployment, it is highly recommended. When you are using this in your environment, if you don't need to resize the gateway, you won't need to specify the -GatewaySku. Application Gateway (Standard_v2 or WAF_v2 SKU) can support up to 125 instances (125 instance IP addresses + 1 private frontend IP configuration + 5 Azure reserved). If they pass the tests, the NVA forwards the packets to the application VM. Allow outbound traffic to the Internet for all destinations. Specify the subscription that you want to use. View all page feedback. Forced tunneling in Azure is configured using virtual network custom user-defined routes. To be able to determine the next address to use for a future gateway and have a contiguous addressing theme for frontend IPs, consider assigning frontend IP addresses from the upper half of the defined subset space. Virtual network peering seamlessly connects two Azure virtual networks, merging the two virtual networks into one for connectivity purposes. See Create a Virtual Machine for steps. Each team then has access to the entire Application Gateway configuration. Azure Firewall Premium forwards the packets to Application Gateway. VPN gateways use the virtual network gateway type VPN. The SKUs listed in the dropdown depend on the VPN type you Network security groups (NSGs) are supported on Application Gateway. In hub-and-spoke network architecture, gateway transit allows spoke virtual networks to share the VPN gateway in the hub, instead of deploying VPN gateways in every spoke virtual network. BGP is required for this configuration. This port range is required for Azure infrastructure communication. WebWhen using site-to-site VPN, by creating a route with a next hop type of VPN Gateway. On the same page, continue on to configure the values for the Remote virtual network. You must complete Part 1 to create and configure TestVNet1 and the VPN Gateway with BGP. You can create a UDR to send 0.0.0.0/0 traffic directly to the Internet. If you name it something else, your gateway creation fails. You don't need to configure anything on the Spoke-Classic VNet. Connecting a virtual network to another virtual network (VNet-to-VNet) is similar to connecting a VNet to an on-premises site location. On the Overview page, select See More to view the private IP address. Advertise disjoint prefixes for VPN and ExpressRoute. Then, prefer the routes with the shortest BGP AS-Path length. Set Use Azure Private IP Address to Enabled, then select Save. Site-to-Site VPN. The network design determines which DNS solution works best, as later sections describe. Only point-to-site connections are impacted; site-to-site connections won't be affected. Setting up VPN Gateway in active-active mode is recommended in which both the IPsec tunnels are simultaneously active, with data flowing through both tunnels at the same time. You can also use the networking service Virtual WAN in this architecture. This allows you to restrict and inspect Internet access from your virtual machines or cloud services in Azure, while continuing to enable your multi-tier service architecture required. This template allows you to deploy a site-to-site VPN between two VNets with VPN Gateways in configuration active-active with BGP. For this configuration, you only need to configure the Hub-RM virtual network. In this example, you see a network within the on-premises network that is connected to the Azure hub VPN gateway over ExpressRoute private peering. In the diagram, gateway transit allows the peered virtual networks to use the Azure VPN gateway in Hub-RM. Select the BGP peer. Establish the VPN connectivity using the steps in this article. The custom Azure APIPA BGP address is needed when your on premises VPN devices use an APIPA address (169.254.0.1 to 169.254.255.254) as the BGP IP. This CIDR must also be in the Azure-reserved APIPA range for VPN, which is from 169.254.21.0 to 169.254.22.255.AWS will use the first IP address of your /30 inside CIDR and Azure will Select Save to save your changes. Visit Add, change, or delete a virtual network subnet to know more on subnet permissions. You need at least 20 IP addresses for this subnet: five for internal use and 15 for the application gateway instances. Scenario 2: UDR to direct 0.0.0.0/0 to the Internet. For planning and design for highly available connections, see Highly available connections. This limitation becomes apparent when Application Gateway and the destination web server are in the same virtual network: Virtual WAN can't force the traffic between Application Gateway and the web server to go through Azure Firewall Premium (a workaround would be manually configuring User Defined Routes in the subnets of the Application Gateway and web server). If a 0.0.0.0/0 (default route) is advertised over BGP through a virtual network gateway when using a site-to-site VPN, or ExpressRoute circuit. Make sure you log in and connect to Subscription 1. If you're using kubenet with Azure Kubernetes Service (AKS) and Application Gateway Ingress Controller (AGIC), you'll need a route table to allow traffic sent to the pods from Application Gateway to be routed to the correct node. An on-premises client connects to the VPN. If you don't already have an Azure subscription, you can activate your, You'll need to install the Azure Resource Manager PowerShell cmdlets if you don't want to use Cloud Shell in your browser. For more information about resizing and migrating SKUs, see Gateway SKUs. The following sections walk through the steps to complete the exercise. In this situation, your 251 - Gateway 1 (10) - 1 private frontend IP configuration = 240 See Highly Available Cross-Premises and VNet-to-VNet Connectivity for an overview of connectivity options and topology. As the subscription owner, you don't have permissions for linking private DNS zones. With a splitted tunneling type you can redirect all the traffic for specific subnets directly to on-premises, instead of other subnet that continue to have direct internet access without redirection. Create the VPN gateway with the AS number and the "EnableActiveActiveFeature" flag. This information is needed when you set up your on premises VPN devices connecting to the active-active gateway. VPN Gateway: Azure Cloud Services and Azure Virtual Machines. If you use PowerShell locally, use the following example to help you connect: The example below declares the variables using the values for this exercise. The Mid-tier and Backend subnets are forced tunneled. Verify that you have an Azure subscription. Consider a subnet that has 27 application gateway instances and an IP address for a private frontend IP. Use the following steps to create or update the virtual network peerings to enable gateway transit. * 2 Site-to site-VPNs terminating at each datacentre based on BGP * Device Tunnels configured with Certificate Authentication on Azure is enabled by advertising a default route via the ExpressRoute BGP peering sessions. If you make a change to the topology of your network and have Windows VPN clients, the VPN client package for Windows clients must be downloaded and installed again in order for the changes to be applied to the client. Generate certificates. View the VPN Gateway FAQ for additional information. These rules help identify malicious files and other threats that target web applications. Make sure that an A record exists for the value that Application Gateway uses for traffic and for health checks. In this case, a client connects from the public internet. Both connectivity types use a VPN gateway to provide a secure tunnel using IPsec/IKE. For steps, see the Configure a Site-to-Site VPN article. Use the diagrams and descriptions to help select the connection topology to match your requirements. Replace the following parameters used for the examples with the settings that you require for your own configuration, then declare these variables. In the event BGP session is dropped between the gateway and Azure Route Server, you'll lose connectivity from your on-premises network to Azure. You can even combine VNet-to-VNet communication with multi-site connection configurations. For information about selecting a VPN device, see the VPN Gateway FAQ - VPN devices. Be sure to replace the values with your own when configuring for production. This will incur downtime and updating the BGP peers on the on-premises devices will be required. Unlike S2S connections, P2S connections do not require an on-premises public-facing IP address or a VPN device. Make sure you add the "-EnableBgp $True" when creating the connections to enable BGP. ExpressRoute forced tunneling is not configured via this mechanism, but instead, is enabled by advertising a default route via the ExpressRoute BGP peering sessions. In this article. You should ensure that the Application Gateway v2 subnet has sufficient address space to accommodate the number of instances required to serve your maximum expected traffic. Within your virtual network, a dedicated subnet is required for the application gateway. Each virtual network subnet has a built-in, system routing table. If forced tunneling is to be adopted, all the subnet must have the default route table overwritten. If the VPN-connected network ranges are disjoint from other ExpressRoute connected networks, you can advertise the prefixes in the VPN and ExpressRoute BGP sessions respectively. Replace the variables and subscription ID with the values of your virtual network and resource groups, and subscription. This document focuses on a common pattern for maximizing security, in which Azure Application Gateway acts before Azure Firewall Premium. With Route Server, customers manage hub virtual networks. You can view the peer on the BGP Peers page. More info about Internet Explorer and Microsoft Edge, Virtual network service endpoint policies, Frequently asked questions about Application Gateway, Add, change, or delete a virtual network subnet, Learn about frontend IP address configuration, Gateway 1: Maximum of 10 instances; utilizes a private frontend IP configuration, Gateway 2: Maximum of 2 instances; no private frontend IP configuration, Gateway 3: Maximum of 15 instances; utilizes a private frontend IP configuration. Logging, metrics, and CRL checks could also be affected. Configure BGP for an Azure VPN Gateway; Use BGP with ExpressRoute; View all routes for a subnet. Point-to-site users connecting to a virtual network gateway can use ExpressRoute (via the Site-to-Site tunnel) to access on-premises resources. If you already have a VPN gateway, you can: You can combine these together to build a more complex, highly available network topology that meets your needs. Forced tunneling can be configured by using Azure PowerShell. Use this private IP as the remote IP on your on-premises firewall to establish the Site-to-Site tunnel over the ExpressRoute private peering. You can disable the automatic route propagation from the VPN gateway. VPN Gateway currently only supports Dynamic Public IP address allocation. Application Gateway sends the packets to the VPN. Establishing connectivity is straightforward: Establish ExpressRoute connectivity with an ExpressRoute circuit and private peering. Link the zone to the virtual network that contains Azure Firewall Premium. For example, in the diagrams above the spoke VNet has the prefix 172.16.0.0/16: in this case, Virtual WAN would not be able to inject a route that matches the VNet prefix (172.16.0.0/16) or any of the subnets (172.16.0.0/24, 172.16.1.0/24). A route injected in the VM subnet by the Route Server redirects the packets to the NVA. Block all other incoming traffic by using a deny-all rule. The diagrams show the main baseline topologies, but it's possible to build more complex configurations using the diagrams as guidelines. For example, advertise 10.0.0.0/16 over ExpressRoute, and 10.0.1.0/24 over VPN. For information about selecting a VPN device, see the VPN Gateway FAQ - VPN devices. This component offers many benefits. Once the gateway is created, you will need to obtain the BGP Peer IP address on the Azure VPN Gateway. Split If you see ValidateSet errors regarding the GatewaySKU value, verify that you have installed the latest version of the PowerShell cmdlets. In the sections below, you can view design information and topology diagrams about the following VPN gateway connections. For more information about VPN Gateway, see What is VPN Gateway? If you have been using Azure for some time, you probably have Azure VMs and instance roles running in a classic VNet. To disable BGP route propagation, use the following steps: Enabling the UDR for this scenario shouldn't break any existing setups. These ports are protected (locked down) by Azure certificates. If your on-premises VPN routers use APIPA IP addresses (169.254.x.x) as the BGP IP addresses, you must specify one or more Azure APIPA BGP IP addresses on your Azure VPN gateway. More info about Internet Explorer and Microsoft Edge, How to install and configure Azure PowerShell. You can also use PowerShell to create or update the peering with the example above. If all the routes are through remote hubs, then choose route from S2S VPN connection over ER connections because any transit between ER to ER is supported only if the circuits have ER Global Reach enabled and an Azure Firewall or NVA is provisioned inside the virtual hub. WebSite-to-Site VPN. The key differences between the active-active and active-standby gateways: The other properties are the same as the non-active-active gateways. Example: SpokeRMtoHubRM, Virtual network gateway: Use the remote virtual network's gateway. (**) denotes that this method contains steps that require PowerShell. Ingress SNAT (BGP-enabled VPN site) Ingress SNAT rules are applied on packets that are entering Azure through the Virtual WAN site-to-site VPN gateway. For example, advertise 10.0.0.0/16 over ExpressRoute, and 10.0.1.0/24 over VPN. If they pass inspection, a UDR in the Application Gateway subnet forwards the packets to Azure Firewall Premium. It's important to know that there are different configurations available for VPN gateway connections. VPN Enable Private IPs on the gateway. This type of security model verifies the trustworthiness of network packets that flow to applications. This article helps you configure gateway transit for virtual network peering. In this configuration, the spoke VNet Spoke-Classic is in the classic deployment model and the hub VNet Hub-RM is in the Resource Manager deployment model. A client sends packets to Application Gateway, a load balancer. The procedure steps set the 'DefaultSiteHQ' as the default site connection for forced tunneling, and configure the 'Midtier' and 'Backend' subnets to use forced tunneling. It was originally written by the following contributors. In this example, the virtual networks belong to the same subscription. This feature is supported on gateways with a standard public IP only. The gateway forwards the client packets to Application Gateway. You can also configure an active-active gateway in the Azure portal. If you treat Application Gateway as a shared resource, you might exceed. Next, take each gateway and subtract the max-instance count. You may see warnings saying "The output object type of this cmdlet will be modified in a future release". This example uses BGP for the cross-premises connection. You may be able to use VNet peering to create your connection, as long as your virtual network meets certain requirements. Creating a gateway can often take 45 minutes or more, depending on the selected gateway SKU. For steps, see the Site-to-site configuration article. WebConfigure point-to-site VPN on the gateway (see Scenario 1). Note that you must override the default ASN on your Azure VPN gateways. Note that there are two GatewayIpConfig entries, and the EnableActiveActiveFeature flag is set. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. VPN Gateway can be configured in active-standby mode using one public IP or in active-active mode using two public IPs. Navigate to the Hub-RM virtual network. The custom Azure APIPA BGP address is needed when your on premises VPN devices use an APIPA address (169.254.0.1 to 169.254.255.254) as the BGP IP. Scenario 3: UDR for Azure Kubernetes Service with kubenet. In this layer, network appliances inspect packets to ensure that only legitimate traffic reaches applications. Configure a Site-to-Site connection. The NVA forwards the packets to Application Gateway. Include a route for 0.0.0.0/0 and a next hop type of Internet in that table. Azure Firewall Premium uses generic intrusion detection and prevention rules. This section helps you change an existing Azure VPN gateway from active-standby to active-active mode, or Before you begin, verify that you have the following virtual networks and permissions: The accounts you use to create a virtual network peering must have the necessary roles or permissions. You can define static routes in virtual hub route tables instead. Set the flag to use the private IP on the gateway using the following PowerShell commands: You should see a public and a private IP address. The gateway SKU must be VpnGw1, VpnGw2, VpnGw3, or HighPerformance (legacy SKU). Use the example below to create a new resource group: The sample below creates a virtual network named TestVNet1 and three subnets, one called GatewaySubnet, one called FrontEnd, and one called Backend. Configure a Site-to-Site connection. Set the connection to use the private IP address by using the following PowerShell command: From your firewall, ping the private IP that you wrote down in step 2. A client submits a request to a web server. You can also use PowerShell to create or update the peering with the example above. The route table should be populated with the following information: Address prefix should be the IP range of the pods you want to reach in AKS. Then, prefer the routes with the shortest BGP AS-Path length. The existing Basic VPN gateway is unchanged with the same 80-100 Mbps For more information, see VNet peering. Next-generation firewalls can also look for generic threats. Peering link name: Name the link. In this step, you will create the connection from TestVNet1 to TestVNet2, and the connection from TestVNet2 to TestVNet1. Forced tunneling lets you redirect or "force" all Internet-bound traffic back to your on-premises location via a Site-to-Site VPN tunnel for inspection and auditing. Viewing all routes shows you the default, BGP, and user-defined routes for the subnet a network interface is in. If you deploy Application Gateway in a dedicated spoke, disable the propagation of the default route in the settings for the virtual network connection. If you're configuring transit between different deployment models, the hub virtual network and virtual network gateway must be in the Resource Manager deployment model, not the classic deployment model. To implement DNS resolution for Azure Firewall Premium, use DNS servers instead: You can only use Virtual WAN to program routes in a spoke if the prefix is shorter (less specific) than the virtual network prefix. Each local network gateway representing a VPN device must have a unique BGP peer IP address specified in the "BgpPeerIpAddress" property. In active-standby mode, one IPsec tunnel is active and the other tunnel is in standby. You can also set up your own custom APIPA addresses. Be sure to enable BGP for BOTH connections. Example: HubRMToSpokeRM, Traffic forwarded from remote virtual network: Allow, Virtual network gateway: Use this virtual network's gateway. ExpressRoute is a direct, private connection from your WAN (not over the public Internet) to Microsoft Services, including Azure. Digital certificates validate each one: In Application Gateway, you deploy the digital certificate that clients see. Use these settings to create and configure the Azure VPN Gateway local network gateways. The VM responds and sets the destination IP address to Application Gateway. If they pass inspection, the Application Gateway subnet forwards the packets to Azure Firewall Premium. For more information, see Virtual network routing table. Virtual network service endpoint policies are currently not supported in an Application Gateway subnet. If your virtual hub advertises a 0.0.0.0/0 route, prevent that route from propagating to the Application Gateway subnet by taking one of these steps: Route Server offers another way to inject routes automatically in spokes. If it doesn't find any threats, it uses zero-trust principles to encrypt the packets. Put the following restrictions on the subnet in this order of priority: Using UDRs on the Application Gateway subnet might cause the health status in the backend health view to appear as Unknown. We recommend that you: Traffic from the AzureLoadBalancer tag with the destination subnet as Any must be allowed. Allow incoming Azure Load Balancer probes (, Allow expected inbound traffic to match your listener configuration (i.e. For cross-premises connectivity through the Internet, use the default Azure VPN gateway settings with encryption and hashing More info about Internet Explorer and Microsoft Edge. Outbound Internet connectivity can't be blocked. Write down this information to use later in the configuration steps. The following diagram illustrates this pattern: Download a Visio file of this architecture. A Site-to-Site (S2S) VPN gateway connection is a connection over IPsec/IKE (IKEv1 or IKEv2) VPN tunnel. Configure a site-to-site tunnel on the Azure virtual network gateway with BGP enabled. The VM responds and sets the destination IP address to the Application Gateway. Before proceeding, please make sure you have completed Part 1 of this exercise. You can also use VPN Gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. You'll use this information in a later step. For information about BGP, see the BGP Overview and How to configure BGP. Each Azure VPN Gateway resolves the FQDN of the remote peers to determine the public IP of the remote VPN Gateway. For the following reasons, it's usually best to treat Application Gateway as an application component and deploy it in a spoke virtual network: With traditional hub and spoke architectures, DNS private zones provide an easy way to use DNS: The following diagram shows the packet flow when Application Gateway is in a spoke virtual network. Establish the Site-to-Site VPN connections. The connection between Application Gateway and the web server only supports TCP port 443, not non-standard ports. Once you obtain a root certificate, you upload the public key information to Azure. Once the gateway is finished provisioning, the new BGP IPs can be obtained and the on-premises device configuration will need to be updated accordingly. For each gateway that has a private frontend IP configuration, subtract one additional IP address per gateway as well. This is to ensure that Application Gateway v2 has sufficient space for autoscaling expansion and maintenance upgrades. Azure Firewall Premium verifies that a well-known CA signs the web server TLS packets. An application gateway is a dedicated deployment in your virtual network. Application Gateway needs to validate those certificates. Azure Firewall Premium assumes a default HTTPS TCP port of 443. Route Server combines the Virtual WAN and hub and spoke variants: The following diagram shows the packet flow when Route Server simplifies dynamic routing. You only need to create virtual network peering on the hub virtual network. The data is encrypted using industry-standard encryption algorithms called IPSec and is then tunneled through the public internet for enhanced security and privacy. To determine the available capacity of a subnet that has existing Application Gateways provisioned, take the size of the subnet and subtract the five reserved IP addresses of the subnet reserved by the platform. To apply encryption to the communication, you must make sure that for the VPN-connected network in Figure 1, Azure routes via the on-premises VPN gateway are preferred over the direct ExpressRoute path. To ensure that the IPsec path is preferred over the direct ExpressRoute path (without IPsec), you have two options: Advertise more specific prefixes on the VPN BGP session for the VPN-connected network. Navigate to the virtual network. S2S connections can be used for cross-premises and hybrid configurations. As a result, you can't associate a DNS private zone with the secure hub that contains Azure Firewall Premium. If the packets pass inspection, the Application Gateway would send the packet to the backend VM. This article helps you configure forced tunneling for virtual networks created using the Resource Manager deployment model. The DNS servers can then resolve the names that Application Gateway uses in HTTP Host headers. Failure to do so might result in incorrect health-probe or traffic-routing behavior. For the v2 SKU, there are supported and unsupported scenarios: An incorrect configuration of the route table could result in asymmetrical routing in Application Gateway v2. You can have multiple instances of a given application gateway deployment in a subnet. Application Gateway (Standard or WAF) SKU can support up to 32 instances (32 instance IP addresses + 1 private frontend IP configuration + 5 Azure reserved) so a minimum subnet size of /26 is recommended. 240 - Gateway 2 (2) = 238 Create the virtual network gateway. Azure Azure VPN Gateway VPN Gateway ( 1, 2 ) Uses a Domain Name System (DNS) service to determine the application virtual machine (VM), Forwards the packets to the application VM, Web Application Firewall uses rules to prevent attacks at the web layer. VPN Gateway: Azure Cloud Services and Azure Virtual Machines. VPN type: Select the VPN type that is specified for your configuration. You might face role-based access control problems if you deploy Application Gateway in the hub. Workflow: Remove any connections to the virtual network gateway. IP addresses are allocated from the beginning of the defined subnet space for gateway instances. Azure Firewall Premium requests DNS resolution from a DNS server in the shared services virtual network. If the peering was already created, you can modify the peering for transit. Certificates are used by Azure to authenticate clients connecting to a VNet over a point-to-site VPN connection. For VPN Gateway BGP considerations, see About BGP. Virtual network peering seamlessly connects two Azure virtual networks, merging the two virtual networks into one for connectivity purposes. A VPN gateway is a specific type of virtual network gateway. Starting July 1, 2018, support is being removed for TLS 1.0 and 1.1 from Azure VPN Gateway. Unauthorized Internet access can potentially lead to information disclosure or other types of security breaches. The VM responds and sets the destination IP address to Application Gateway. If all the routes are through remote hubs, then choose route from S2S VPN connection over ER connections because any transit between ER to ER is supported only if the circuits have ER Global Reach enabled and an Azure Firewall or NVA is provisioned inside the virtual hub. For capacity planning around instance count, see instance count details. Azure Firewall Premium runs security checks on the packets. The functionality of the NVA in the hub determines whether your implementation needs DNS. Application Gateway intercepts the client packets and examines them. Note these points: As with Virtual WAN, you might need to modify the routing when you use Route Server. P2S connections can be used with S2S connections through the same VPN gateway, as long as all the configuration requirements for both connections are compatible. Connectivity available on the VPN gateway, including S2S, P2S, and VNet-to-VNet connections, applies to all three virtual networks. This breaks management plane traffic, which In this situation, access to Application Gateway is from an on-premises network. It's possible to deploy Site-to-Site VPN connections over ExpressRoute private peering at the same time as Site-to-Site VPN connections via the Internet on the same VPN gateway. VNet peering does not use a virtual network gateway. This solution is useful for telecommuters who want to connect to Azure VNets from a remote location, such as from home or a conference. VPN (PolicyBased RouteBased) VPN VPN Azure Firewall Premium establishes a TLS session with the destination web server. Once the status shows Connected, the spoke virtual network can use the connectivity through the VPN gateway in the hub virtual network. The system routing table has the following three groups of routes: Forced tunneling must be associated with a VNet that has a route-based VPN gateway. Azure currently has two deployment models: classic and Resource Manager. In this scenario, the virtual networks are both in the Resource Manager deployment model. Scenario 1: UDR to disable Border Gateway Protocol (BGP) Route Propagation to the Application Gateway subnet. Your forced tunneling configuration will override the default route for any subnet in its VNet. Create the connection from TestVNet1 to Site5_2 with "EnableBGP" set to $True. For more information about Point-to-Site VPN, including supported protocols, see About Point The example below lists the parameters you will enter into the BGP configuration section on your on-premises VPN device for this exercise: The connection should be established after a few minutes, and the BGP peering session will start once the IPsec connection is established. This configuration provides the following benefits: Traffic over private peering is encrypted. As a result: The following diagram shows the common names (CNs) and certificate authorities (CAs) that the architecture's TLS sessions and certificates use: This architecture contains three distinct TLS connections. If you want to configure forced tunneling for the classic deployment model, see Forced tunneling - classic. By default, Azure assigns a private IP address from the GatewaySubnet prefix range automatically as the Azure BGP IP address on the Azure VPN gateway. After declaring the variables, get the name of the IP configuration you want to remove. Don't create other outbound rules that deny any outbound connectivity. But Web Application Firewall can be a shared network device or an application-specific component. By default, Azure assigns a private IP address from the GatewaySubnet prefix range automatically as the Azure BGP IP address on the Azure VPN gateway. For example, you can set up a UDR in the Application Gateway subnet to point to a firewall appliance for packet inspection. The workloads in the Frontend subnet can continue to accept and respond to customer requests from the Internet directly. Be sure to replace the values with the ones that you want to use for your configuration. VPN Site 1 connects via Link A, and VPN Site 2 connects via Link B. VPN Gateway can be configured in active-standby mode using one public IP or in active-active mode using two public IPs. Azure VPN Gateway selects the APIPA addresses to use with the on-premises APIPA BGP peer specified in the local network gateway, or the private When substituting values, it's important that you always name your gateway subnet specifically GatewaySubnet. The latest version of the PowerShell cmdlets contains the new validated values for the latest Gateway SKUs. The NVA runs security checks on the packets. A multilayered approach works best, where network security makes up one layer. Replace the variables with the names of your virtual networks and resource groups. VPN Gateway will support only TLS 1.2. This address is needed to configure the Azure VPN Gateway as a BGP Peer for your on-premises VPN devices. Click at the end of the line for the peer, then select Edit from the dropdown. But Application Gateway doesn't support that route. In this example, the Azure VPN gateway is in active-active mode. A UDR in the VM subnet redirects the packets to Azure Firewall Premium. As instances are created and removed due to creation of gateways or scaling events, it can become difficult to understand what the next available address is in the subnet. The application gateway infrastructure includes the virtual network, subnets, network security groups, and user defined routes. Use the private IP that you wrote down in step 3 as the remote IP on your on-premises firewall to establish the Site-to-Site tunnel over the ExpressRoute private peering. Learn about some of the other key networking capabilities of Azure. The value of the HTTP Host header should resolve to that IP address. Resetting an Azure VPN gateway is helpful if you lose cross-premises VPN connectivity on one or more site-to-site VPN tunnels. If your on-premises VPN routers use APIPA IP addresses (169.254.x.x) as the BGP IP addresses, you must specify one or more Azure APIPA BGP IP addresses on your Azure VPN gateway. Installing the latest version of the PowerShell cmdlets is required. This article helps you understand how Azure Point-to-Site VPN routing behaves. In the Azure portal, create or update the virtual network peering from the Hub-RM. Download the point-to-site profile from the Azure portal and distribute to clients The following diagram shows the packet flow in a case that uses Virtual WAN. Gateway transit is a peering property that lets one virtual network use the VPN gateway in the peered virtual Default outbound rules in the NSG allow Internet connectivity. WebVPN Gateway documentation. The VM responds and sets the destination IP address to Application Gateway. As a result, you can link the hub virtual network to a DNS private zone. Site-to-Site VPN offers a simple and secure way to connect your corporate network to Oracle Cloud Infrastructure over your existing internet connection. You can configure a Site-to-Site VPN as a secure failover path for ExpressRoute, or use Site-to-Site VPNs to connect to sites that are not part of your network, but that are connected through ExpressRoute. If you advertise the same prefixes over both ExpressRoute and VPN connections, >Azure will use the ExpressRoute path directly without VPN protection. Be sure to replace the values with the ones that you want to use for your configuration. 2 Please be aware of the ExpressRoute Private Peering limit of 1000 routes per connection from Virtual Network Gateway towards ExpressRoute circuit. With this design, you might need to modify the routing that the hub advertises to the spoke virtual networks. Specifically, Application Gateway v2 only supports a 0.0.0.0/0 route that points to the internet. Select Configuration, then set Gateway Private IPs to Enabled. The gateway IP address, address prefix, and BGP peering address for the second local network gateway must not overlap with the previous local network gateway for the same on-premises network. If you are working with the Resource Manager deployment model, you can change to the new gateway SKUs. Key Differences. A couple of things to note regarding the local network gateway parameters: Before you continue, please make sure you are still connected to Subscription 1. Assign a default site to the virtual network gateway. Azure VPN Gateway selects the APIPA addresses to use with the on-premises APIPA BGP peer specified in the local network gateway, or the private After declaring the variables, you can copy and paste this example to your PowerShell console. Application Gateway and Azure Firewall Premium handle certificates differently from one another because their roles differ: Application Gateway is a reverse For more information, see the ExpressRoute Documentation. Request two public IP addresses to be allocated to the gateway you will create for your VNet. This exercise will continue to build the configuration shown in the diagram. You should use BGP to advertise the same prefixes of the same on-premises network prefixes to your Azure VPN gateway, and the traffic will be If there are no Internet-facing workloads in your virtual networks, you also can apply forced tunneling to the entire virtual networks. This article helps you configure gateway transit for virtual network peering. Next hop address should be the IP address of the node hosting the pods. Azure also reserves five IP addresses in each subnet for internal use: the first four and the last IP addresses. Submit and view feedback for. To achieve high availability for cross-premises and VNet-to-VNet connectivity, you should deploy multiple VPN gateways and establish multiple parallel connections between your networks and Azure. A S2S connection requires a VPN device located on-premises that has a public IP address assigned to it. Be sure to pick a gateway with a Standard Public IP. For example, if you want to create a S2S VPN gateway connection and a P2S VPN gateway connection for the same virtual network, you would use VPN type RouteBased because P2S requires a RouteBased VPN type. Peering link name: Name the link. Additional resources. For example, here's how to calculate the available addressing for a subnet with three gateways of varying sizes: Subnet Size /24 = 256 IP addresses - 5 reserved from the platform = 251 available addresses. It also might cause generation of Application Gateway logs and metrics to fail. For this configuration, you don't need to configure anything on the Spoke-Classic virtual network. SKU: Select the gateway SKU you want to use from the dropdown. In this example, the Frontend subnet is not force tunneled (split tunneling). Install the latest version of the Azure Resource Manager PowerShell cmdlets. If there is only one on-premises VPN device as shown above, the active-active connection can work with or without BGP protocol. Redirecting traffic to an on-premises site is expressed as a Default Route to the Azure VPN gateway. The following diagram shows how gateway transit works with virtual network peering. Learn more about VPN Gateway configuration settings. If you have more than one subscription, get a list of your Azure subscriptions. A S2S connection requires a VPN device located on-premises that has a public IP address assigned to it. Web application firewalls look for patterns that indicate an attack at the web application layer. A minimum subnet size of /24 is recommended. Verify the subscription is correct, then select the virtual network from the dropdown. After completing these steps, the connection will be establish in a few minutes, and the BGP peering session will be up once the VNet-to-VNet connection is completed with dual redundancy: When you change an active-standby gateway to active-active, you create another public IP address, then add a second Gateway IP configuration. When you change from a legacy gateway SKU to a new SKU, you delete the existing VPN gateway and create a new VPN gateway. To apply encryption to the communication, you must make sure that for the VPN-connected network in Figure 1, Azure routes via the on-premises VPN gateway are preferred over the direct ExpressRoute path. Create the resource group if it is not yet created. This situation can come up when teams manage different applications but use the same instance of Application Gateway. Site-to-Site VPN traffic travels encrypted over the public Internet. As a result, even though there is only one on-premises VPN device (local network gateway) and one connection resource, both Azure VPN gateway instances will establish S2S VPN tunnels with the on-premises device. Application Gateway examines the packets. To decrypt and inspect TLS traffic, Azure Firewall Premium dynamically generates certificates. A site-to-site VPN or ExpressRoute connects that network to Virtual WAN. After you authenticate, it downloads your account settings so that they're available to Azure PowerShell. Write down the IP address under the TunnelIpAddresses section of the output. Application Gateway and Azure Firewall Premium handle certificates differently from one another because their roles differ: Typically, a hub and spoke design deploys shared network components in the hub virtual network and application-specific components in the spokes. A P2S connection is established by starting it from the client computer. In this step, you enable active-active mode and update the gateway. You can reach resources over RFC1918 (private) IP in the VNet over the ExpressRoute circuit. In other words, Virtual WAN cannot attract traffic between two subnets that are in the same VNet. An additional advantage of active-active mode is that customers experience higher throughputs. In this procedure, the virtual network 'MultiTier-VNet' has three subnets: 'Frontend', 'Midtier', and 'Backend', with four cross-premises connections: 'DefaultSiteHQ', and three Branches. All VPN tunnels of the virtual network share the available bandwidth on the Azure VPN gateway and the same VPN gateway uptime SLA in Azure.
