Please help! Cod4 Problems!!

[MeBetterThanYou]

Hi everyone! Im brand new to this site, so be easy on me. I have just purchased cod4 on the app store, and just wanted multiplayer. Every time I try to play, it says I need to be connected to a network. And I am! I have tried 3 different ones. Please help!
Thanks!

That is not an ambiguous error message. You are doing something wrong, or your network is blocking the ports the game is using. Google around to see what ports you need to open.

Agree with Miles, you probably don't have the ports that game requires open.

check your documentation and see what ports and/or protocol COD4 expects and see if that is how you have your router set up.
