This thread has been very helpful, so Id like to share what my friend and I have learned.
Need for Speed Underground 2 uses the following TCP and UDP port(s) for Internet play:
TCP ports:
80
13505
20920-20929 - This is a range of ports and all ports within this range will need to be opened.
20970-20979 - This is a range of ports and all ports within this range will need to be opened.
UDP port addresses:
3658
3659
- Ports 20900-20999 are TCP and are outgoing ports for connecting to the Lobby server.
- Port 13505 is TCP and is an outgoing port for connecting to the EA Messenger (buddy list) server.
- Ports 3658 & 3659 are UDP and are incoming/outgoing ports for connecting to another user to play a game.
- Port 6000 is UDP and is an incoming/outgoing port for connecting to another user for headset use during a game.
This was taken from :

and

Note the lobby ports, perhaps it will help those of you able to see the game and unable to join the lobby.
Also If someone would create a wizard file for it, that would be most helpful.[/b]
