     If you look further down you'll see that the OP's problem was bad 
firmware on a $12 router.  Having said that there are some ports that 
are needed for voice chat which does seem to have a peer to peer 
component.  I also run gaming servers for my own enjoyment (TF2 
currently and many others in the past) and the days of hosting your own 
$fps_game server are generally past and very much outside of the public 
norm even for PC gaming.  While you can do that the vast majority of the 
gaming hours today are spent on servers hosted by companies like Nuclear 
Fallot, Branzone, and a host of others.  I do miss the days of Quake but 
home hosted game servers are a dying (but not completely dead) breed.
