Create a route-based VPN gateway using PowerShell

This article helps you quickly create a route-based Azure VPN gateway using PowerShell. A VPN gateway is used when creating a VPN connection to your on-premises network. You can also use a VPN gateway to connect VNets.

Before you begin

The steps in this article will create a VNet, a subnet, a gateway subnet, and a route-based VPN gateway (virtual network gateway). Once the gateway creation has completed, you can then create connections. These steps require an Azure subscription. If you don't have an Azure subscription, create a free account before you begin.

Working with Azure PowerShell

This article uses PowerShell cmdlets. To run the cmdlets, you can use Azure Cloud Shell. The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com/powershell. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press enter to run it.

You can also install and run the Azure PowerShell cmdlets locally on your computer. PowerShell cmdlets are updated frequently. If you have not installed the latest version, the values specified in the instructions may fail. To find the versions of Azure PowerShell installed on your computer, use the Get-Module -ListAvailable Az cmdlet. To install or update, see Install the Azure PowerShell module.

Create a resource group

Create an Azure resource group with New-AzResourceGroup. A resource group is a logical container into which Azure resources are deployed and managed. Create a resource group. If you are running PowerShell locally, open your PowerShell console with elevated privileges and connect to Azure using the Connect-AzAccount command.

New-AzResourceGroup -Name TestRG1 -Location EastUS

Create a virtual network

Create a virtual network with New-AzVirtualNetwork. The following example creates a virtual network named VNet1 in the EastUS location:

$virtualNetwork = New-AzVirtualNetwork `
  -ResourceGroupName TestRG1 `
  -Location EastUS `
  -Name VNet1 `
  -AddressPrefix 10.1.0.0/16

Create a subnet configuration using the New-AzVirtualNetworkSubnetConfig cmdlet.

$subnetConfig = Add-AzVirtualNetworkSubnetConfig `
  -Name Frontend `
  -AddressPrefix 10.1.0.0/24 `
  -VirtualNetwork $virtualNetwork

Set the subnet configuration for the virtual network using the Set-AzVirtualNetwork cmdlet.

$virtualNetwork | Set-AzVirtualNetwork

Add a gateway subnet

The gateway subnet contains the reserved IP addresses that the virtual network gateway services use. Use the following examples to add a gateway subnet:

Set a variable for your VNet.

$vnet = Get-AzVirtualNetwork -ResourceGroupName TestRG1 -Name VNet1

Create the gateway subnet using the Add-AzVirtualNetworkSubnetConfig cmdlet.

Add-AzVirtualNetworkSubnetConfig -Name 'GatewaySubnet' -AddressPrefix 10.1.255.0/27 -VirtualNetwork $vnet

Set the subnet configuration for the virtual network using the Set-AzVirtualNetwork cmdlet.

$vnet | Set-AzVirtualNetwork

Request a public IP address

A VPN gateway must have a dynamically allocated public IP address. When you create a connection to a VPN gateway, this is the IP address that you specify. Use the following example to request a public IP address:

$gwpip= New-AzPublicIpAddress -Name VNet1GWIP -ResourceGroupName TestRG1 -Location 'East US' -AllocationMethod Dynamic

Create the gateway IP address configuration

The gateway configuration defines the subnet and the public IP address to use. Use the following example to create your gateway configuration:

$vnet = Get-AzVirtualNetwork -Name VNet1 -ResourceGroupName TestRG1
$subnet = Get-AzVirtualNetworkSubnetConfig -Name 'GatewaySubnet' -VirtualNetwork $vnet
$gwipconfig = New-AzVirtualNetworkGatewayIpConfig -Name gwipconfig1 -SubnetId $subnet.Id -PublicIpAddressId $gwpip.Id

Create the VPN gateway

A VPN gateway can take 45 minutes or more to create. Once the gateway has completed, you can create a connection between your virtual network and another VNet. Or, create a connection between your virtual network and an on-premises location. Create a VPN gateway using the New-AzVirtualNetworkGateway cmdlet.

New-AzVirtualNetworkGateway -Name VNet1GW -ResourceGroupName TestRG1 `
-Location 'East US' -IpConfigurations $gwipconfig -GatewayType Vpn `
-VpnType RouteBased -GatewaySku VpnGw1

View the VPN gateway

You can view the VPN gateway using the Get-AzVirtualNetworkGateway cmdlet.

Get-AzVirtualNetworkGateway -Name Vnet1GW -ResourceGroup TestRG1

The output will look similar to this example:

Name                   : VNet1GW

View the public IP address

To view the public IP address for your VPN gateway, use the Get-AzPublicIpAddress cmdlet.

Get-AzPublicIpAddress -Name VNet1GWIP -ResourceGroupName TestRG1

In the example response, the IpAddress value is the public IP address.

Name                     : VNet1GWIP
ResourceGroupName        : TestRG1
Location                 : eastus

Clean up resources

When you no longer need the resources you created, use the Remove-AzResourceGroup command to delete the resource group. This will delete the resource group and all of the resources it contains.

Remove-AzResourceGroup -Name TestRG1

Next steps

Once the gateway has finished creating, you can create a connection between your virtual network and another VNet. Or, create a connection between your virtual network and an on-premises location.
