Quote from Becky Rose :

Yes it is only 1 port. Multiple connections can exist on the same port - I dont know why some programmers feel it necessary to write their games across multiple ports it just doesnt make sense to do this from a security point of view - but some programmers do... They're strange people and should be shot - thankfully LFS uses just the 1 port, which is how all multiplayer games should be written. /opinion off

The LFS developer's brilliance runs even deeper! You can choose which port number you want, and even run multiple hosts on the same machine!
The thing to remember when setting up port forwarding is that you open TCP AND UDP, IN AND OUT for the port number or numbers of choice. That way your only concern is bandwidth!
