Virtual Network Gateway VPN Client Connection Cmdlets

Azure Virtual Network Gateway VPN Client Connection Cmdlets

This section provides a comprehensive reference for PowerShell cmdlets used to manage VPN client connections for Azure Virtual Network Gateways. These cmdlets enable you to configure, monitor, and troubleshoot client VPN connections, facilitating secure access to your Azure resources.

Scenarios and Corresponding Cmdlets

The following table outlines common scenarios for VPN client connections and the primary PowerShell cmdlets associated with them:

Scenario Description Primary Cmdlets
Get VPN Client Configuration Retrieve the VPN client configuration package for a virtual network gateway. This package is used to connect VPN clients to your Azure network. Get-AzVpnClientConfiguration
Download VPN Client Package Download the generated VPN client configuration package. Get-AzVpnClientConfiguration -VpnPackageUrl (URL provided in output)
List VPN Client Connection Status View the status of active VPN client connections to the gateway. Get-AzVirtualNetworkGatewayVpnConnection
Disable VPN Client Access Revoke the ability for a specific client to connect. Remove-AzVpnClientConnection (Note: This cmdlet might be used indirectly or for specific revocation scenarios, direct disable might involve policy updates or client certificate management)
Configure Client Certificate Authentication Manage client certificates for authentication with the VPN gateway. Add-AzVpnClientRootCertificate, Get-AzVpnClientRootCertificate, Remove-AzVpnClientRootCertificate
Configure Pre-Shared Key (PSK) Authentication Set up shared key authentication for point-to-site VPN connections. Set-AzVirtualNetworkGatewayIpConfig (via BGP settings or associated connection configurations)
Monitor Connection Health Check the overall health and performance of VPN client connections. Get-AzVirtualNetworkGatewayConnectionHealth

Key Cmdlets Deep Dive

Get-AzVpnClientConfiguration

This cmdlet is fundamental for setting up point-to-site VPN connections. It generates and provides a URL to download a VPN client configuration package tailored for your Azure VPN gateway. This package contains all necessary settings, certificates, and scripts for end-users to establish a VPN connection from their devices.

# Example: Get the VPN client configuration for a gateway
Get-AzVpnClientConfiguration -VirtualNetworkGatewayName "MyVpnGateway" -ResourceGroupName "MyResourceGroup"

Get-AzVirtualNetworkGatewayVpnConnection

Use this cmdlet to retrieve information about established VPN connections, including active client sessions, their IP addresses, and connection duration.

# Example: Get all active VPN connections for a gateway
Get-AzVirtualNetworkGatewayVpnConnection -VirtualNetworkGatewayName "MyVpnGateway" -ResourceGroupName "MyResourceGroup"

Certificate Management Cmdlets

Cmdlets like Add-AzVpnClientRootCertificate are crucial for implementing certificate-based authentication, a more secure alternative to Pre-Shared Keys for enterprise deployments.

# Example: Add a root certificate for client authentication
Add-AzVpnClientRootCertificate -VirtualNetworkGatewayName "MyVpnGateway" -ResourceGroupName "MyResourceGroup" -Name "MyRootCert" -CertificateData (Get-Content -Path "C:\path\to\your\rootcert.cer" -Encoding Byte -ReadCount 0)
