Hello,
Recently i just started playing Faces of War again and having issues creating a room.

The error is: The server is behind a non-promiscuous nat and does not support negotiation Close current game session?

This is really frustrating i am trying to play with my clan mate and we can't host our own game online.. I would join other servers/rooms but everyone only likes doing tanks only or w/e.. I like doing tanks and infantry so i like to create my own rooms, if anyone can help it'd be greatly appreciated.

I think you cannot host a game if you're behind NAT. Does your friend have a NAT? If not, then he can host a game.

WHat do you mean behind NAT, i have this problem in COH too, maybe its the same thing?
