The easiest way to deal with this situation is with UPnP, but it's  
insecure and shouldn't be done unless you want to run the risk.  
However, I've been running it for a while, and haven't had any  
problems. Anyway, it allows compatible torrent programs (Azureus and  
others) , along with other programs that support it, to dynamically  
forward ports to the computer that it's running on. As for different  
ports, it doesn't matter what port you run bittorrent on, so long as  
it's forwarded.
