Firewall/NAT

I need help setting up the Rules and Nat for Call of Duty 4.  It asks for port 28960 UDP.  So i added 28960 UDP and TCP to the server address, and i cant see the game server or my friends.  I did the same thing for Americas Army last night and that ran fine.  Could Somebody give me a hand with this please.

Is anybody going to help out IRC there are people there but nobody talks.

not sure if this will help but.

when you run the game have a Netstat session in dos running on the pc you are running call of duty on and see what ports its trying to use and then see if you can add these to the Port forward section ?
