I installed Wireguard on a Windows server with the IP address 192.168.100.2. The Tunnel address is 10.0.0.1 on the server and 10.0.0.2 on the client. In the GWN7000 I forwarded the port 52800 for the Wireguard listening port of the server from the WAN to the server address. Thus I can ping this port from the client.
In order to get the UDF traffic through the VPN tunnel, what Source address do I need to enter in the Output firewall settings; the server address 192.168.100.2 or the Tunnel address 10.0.0.1 ?
