This documentation provides a comprehensive overview of the Azure PowerShell cmdlets designed for troubleshooting VPN client connections to Azure Virtual Network Gateways. These cmdlets help diagnose and resolve common connectivity issues, ensuring seamless and secure communication between your on-premises networks and Azure resources.
Update-Module -Name Az to update your modules.
Retrieves information about active VPN client connections to your Azure Virtual Network Gateway.
Tests the connectivity of a specific VPN client connection, reporting success or failure with diagnostic details.
Initiates a troubleshooting session for a specific VPN client connection, generating a report with potential solutions.
Retrieves the VPN client configuration settings for your Azure Virtual Network Gateway.
Configures VPN client settings, including address pools and authentication methods, for your gateway.
Use Test-AzVirtualNetworkGatewayVpnClientConnection to verify basic connectivity and authentication. If issues persist, run Invoke-AzVirtualNetworkGatewayVpnClientConnectionTroubleshoot to get a detailed report.
# Connect to your Azure subscription
Connect-AzAccount
# Set your context to the correct subscription and resource group
Select-AzSubscription -SubscriptionId "YOUR_SUBSCRIPTION_ID"
$resourceGroupName = "MyResourceGroup"
$gatewayName = "MyVpnGateway"
# Get information about active connections
Get-AzVirtualNetworkGatewayVpnClientConnection -VirtualNetworkGatewayName $gatewayName -ResourceGroupName $resourceGroupName
# Test a specific connection (if you have the client IP)
# Test-AzVirtualNetworkGatewayVpnClientConnection -VirtualNetworkGatewayName $gatewayName -ResourceGroupName $resourceGroupName -ClientIp "192.168.1.100"
# Initiate a full troubleshooting session
Invoke-AzVirtualNetworkGatewayVpnClientConnectionTroubleshoot -VirtualNetworkGatewayName $gatewayName -ResourceGroupName $resourceGroupName -ClientIp "192.168.1.100" | Out-String -Stream
Check the status of active connections using Get-AzVirtualNetworkGatewayVpnClientConnection. Review the gateway's performance metrics in the Azure portal and consider adjustments to the VPN client configuration or the gateway's SKU using Set-AzVirtualNetworkGatewayVpnClientConfiguration.
Verify that the VPN client configuration on both the Azure gateway and the client device matches. Ensure the correct authentication type (e.g., IKEv2, SSTP) and any pre-shared keys or certificates are accurately configured. Use Get-AzVirtualNetworkGatewayVpnClientConfiguration to review the gateway's settings.
For complex issues, leverage the detailed logs and diagnostic outputs provided by the troubleshooting cmdlets. You may need to correlate this information with logs from your on-premises VPN devices and client operating systems.
The output of Invoke-AzVirtualNetworkGatewayVpnClientConnectionTroubleshoot often contains specific error messages and recommended actions. Pay close attention to:
The cmdlets Get-AzVirtualNetworkGatewayVpnClientConfiguration and Set-AzVirtualNetworkGatewayVpnClientConfiguration are crucial for understanding and modifying the gateway's VPN client settings. These include:
