I think this is just for Steam, not sure though, but people having connection problems should try port forwarding these:

TCP: 80
18121
18126
18505
UDP: 18126

After doing this, Updating Stats and Waiting For Data takes a fraction of the time. I'm still getting random EA online problems though. I think as far as that goes it's luck of the draw?

Also after opening these ports I actually get my rank and next unlock etc showing up properly in the main menu

GL people, this is one frustrating release for some.

if you read the scrolly thing at the bottom theres a small fix for it, and it fixed my problem...

uninstall the beta, and run the pbweb client.
fixed my random EA connection errors.

im convinced they're not the ports it uses. I think the beta used those ports but if i run bc2 and TCPview none of those ports are in the list.

Hmm I dunno, all I know is, something happened after I did it haha. I already uninstalled the beta. Haven't updated PB though...

I have never loved and hated a game this much. Seriously, if the gameplay was average I would have given up ages ago.

The retail version including the steam version use these ports

18390 TCP Outgoing
18395 TCP Outgoing
18395 UDP Outgoing
13505 TCP Outgoing
80 TCP Outgoing
