I'm asking here because I know there are people here with loads of GTA experience so you might have the answer.
Basically I need to know the ports I need (and preferably less than about 5 because my main server is stingy with opening up ports) that I would need to play the TCP/IP GTA multiplayer (I've just downloaded it again you see).
It's annoying that it can't find my friend's game because we're on a huge LAN here at uni halls but until the relevant port is opened we won't be able to find each other's games =(
