Azure Virtual Network Gateway VPN Client Connection Cmdlets

Cmdlet Overview

The following cmdlets are available for managing VPN client connections. They enable you to generate client configuration packages, retrieve connection status, and manage various aspects of the VPN client experience.

• Get-AzVpnClientConfiguration
  Retrieves the VPN client configuration for a virtual network gateway. This allows you to download configuration files for various VPN client types.
  Parameters: -VirtualNetworkGatewayName (String): The name of the virtual network gateway.
  -ResourceGroupName (String): The name of the resource group.
  -VpnClientProtocol (String): The VPN client protocol (e.g., IKEv2, VpnClientProtocol.All).
• Get-AzVpnClientConnectionHealth
  Gets the connection health of VPN clients connected to a virtual network gateway.
  Parameters: -VirtualNetworkGatewayName (String): The name of the virtual network gateway.
  -ResourceGroupName (String): The name of the resource group.
• Get-AzVpnClientConnectionUsage
  Gets the usage statistics for VPN clients connected to a virtual network gateway.
  Parameters: -VirtualNetworkGatewayName (String): The name of the virtual network gateway.
  -ResourceGroupName (String): The name of the resource group.
• New-AzVpnClientRootCertificate
  Creates a new root certificate for a virtual network gateway.
  Parameters: -VirtualNetworkGatewayName (String): The name of the virtual network gateway.
  -ResourceGroupName (String): The name of the resource group.
  -Name (String): The name of the root certificate.
  -PublicCertDataBase64 (String): The Base64 encoded public certificate data.
• Remove-AzVpnClientRootCertificate
  Removes a root certificate from a virtual network gateway.
  Parameters: -VirtualNetworkGatewayName (String): The name of the virtual network gateway.
  -ResourceGroupName (String): The name of the resource group.
  -Name (String): The name of the root certificate to remove.

Design Templates and Use Cases

These cmdlets are often used in conjunction with design templates for setting up secure remote access to Azure resources. Here are some common scenarios:

Scenario 1: Downloading Client Configuration for P2S VPN

To enable your users to connect to your Azure virtual network using Point-to-Site (P2S) VPN, you need to provide them with a client configuration package. This package contains the necessary certificates and settings.

# Sign in to your Azure account
Login-AzAccount

# Set your subscription context
Set-AzContext -SubscriptionId ""

# Define resource group and gateway name
$resourceGroupName = "MyResourceGroup"
$gatewayName = "myVpnGateway"

# Get the client configuration for IKEv2
Get-AzVpnClientConfiguration -VirtualNetworkGatewayName $gatewayName -ResourceGroupName $resourceGroupName -VpnClientProtocol IKEv2 -OutputFolder .\ClientConfig
Write-Host "VPN client configuration downloaded to .\ClientConfig"

Scenario 2: Monitoring VPN Client Connectivity

You can use these cmdlets to monitor the health and usage of your VPN client connections, which is crucial for troubleshooting and ensuring optimal performance.

# Sign in to your Azure account
Login-AzAccount

# Set your subscription context
Set-AzContext -SubscriptionId ""

# Define resource group and gateway name
$resourceGroupName = "MyResourceGroup"
$gatewayName = "myVpnGateway"

# Get VPN client connection health
Get-AzVpnClientConnectionHealth -VirtualNetworkGatewayName $gatewayName -ResourceGroupName $resourceGroupName
