Failed to connect to server

[mrsmiley]

Every time I try to connect to a server it gives me the You Have Failed To Connect message. Fresh install, just installed it, and yes everything is allowed on my firewalls. Pretty sure my problem is I just need to forward some ports, but I couldn't find anything with the search function. Is there a connection guide on port forwarding? Or if someone could just post a list of ports that need to be forwarded that would be nice. The only connection issue I am having is with initially connecting to a server from the server list, so if anyone knows what ports need to be forwarded for that I would be pretty appreciative.

Edit - Nvm, searched the ports for Battlefield 2 and opened them and it worked. Now I just have to deal with this invalid cd-key message bs.
