AZURE VPN GATEWAYS SUPPORT OPEN-VPN
Azure networking product team announced the General Availability (GA) of OpenVPN protocol in Azure VPN gateways for P2S connectivity. OpenVPN is open-source software that implements a virtual private network (VPN) connectivity. Since OpenVPN is widely used in many industries, a lot of devices already have an OpenVPN client built-in. OpenVPN support for Azure VPN gateways should make it easy to set up new VPN connectivity to Azure virtual networks.
To use the OpenVPN just simply select the tunnel type OpenVPN. You can find more information about how to set up an Azure VPN gateway on here.
To enable OpenVPN on your gateway you can run the following Azure PowerShell commands. Make sure that the gateway is already configured for point-to-site (IKEv2 or SSTP) before running the following commands:
$gw = Get-AzVirtualNetworkGateway -ResourceGroupName $rgname -name $name Set-AzVirtualNetworkGateway -VirtualNetworkGateway $gw -VpnClientProtocol OpenVPN
