Thanks Dave, I managed to find my outside/routers IP address but CMSF wont connect to it from my friends PC...its not offered as the IP address in game, which is clearly the local network one. All I need to know is how the heck do I come up with a connection ?? very frustrating Thanks for helping though.
Port 7023 is open though. We have managed to connect in the past, but this interal ip thing is very confusing
