I assume you mean OpenVPN server. There's also a PPTP server. Helps to be more specific.

Are you actually accessing the WAN from the internet side, OR, just referencing the WAN ip from inside the same LAN that's hosting the OpenVPN server (aka, NAT loopback)? Because if you're using NAT loopback, it won't work. You need to be on the internet side of the WAN (e.g., cellular network of your smartphone, a neighbor's wifi, etc.).
