Fore note: I've never played CO-OP.

If I have two licenses to FC4 can I play CO-OP locally on my own internal network or do both of us have to join a server on the internet? Since my ISP only really has one IP address connection I could foresee problems if we both tried to use the same internet connection.

But if I can have one of my PC's start a game locally and then have the other join that would work.

BUT is it possible to do?
