No I am not doing AFS to the open internet just internal.  My daughter 
is starting to want to play WoW.  This requires a set of ports to be 
mapped to the IP of the system playing the game.  I play on my computer 
and as long as I am the only one playing it is not an issue.  With her 
starting to play on her computer that will become an issue for updates, 
voice chat, and much more.  I can not change the RED ports, thus my idea 
of using BLUE.
