Right, which is why I added the DNAT rules.  Basically, as I understand 
it, those rules should route unsolicited packets (new packets) to the 
machine that I'm using as the game client.  This way, the game server 
can talk to the client...

But, as I write this, I'm wondering if those packets are being ignored, 
because I have my "lock down" rule first, in the FORWARD table!!!  I.e., 
before I set the FORWARD rules for the specific ports, I have a general 
ruile that says if the connection is NEW, drop it!!!

I think I just solved my problem!
