1) Can anyone tell me what ports Crysis 3 uses/needs to use so I can try and get an open NAT type on PS3? EA phone support are apparently closed on a sunday and I can't seem to find any info online, only Crysis and Crysis 2, will the ports be the same?

2) Also if anyone knows how do you solve the problem of joining a friends squad, whenever I try it tells me he's running an out-dated multiplayer version, we have tried leaving multiplayer, resetting etc, the only thing that works is reinstalling game data WTF.

Any help for either of these? cheers.

Every 1 I know is on moderate for nat type even if you have open nat on every over game. So I wouldn't worry to much about that. They need to fix the servers on ps3 and then it properly be fine.
