After sending my first message, I found that my question of uPNP had
been answered in previous threads, so I've changed my subject in hopes
of getting a solution.
I have a game system that needs ports forwarded to it, but each game
needs different ports.
I could put it in a DMZ, but I have a cable modem with one dynamic IP
address, so I can't simply forward all ports for one address to the
machine in the DMZ.
From what I understand, I need uPNP. Is there another way to do this?
