Ok, I have a Linksys WRT54G router as well as a Speedstream 4200. Every time I try forwarding ports to the Static IP of my PS3 I get this error message:

NAPT Server IP address is not a valid LAN host address.

And whenever I try it with the DMZ, I get this error message:

DMZ host IP address is not a valid LAN host address.

Unplugging the one ethernet cord on my Speedstream will kick me offline on here, so I do I fix this where I can be online on my computers, and my game systems at the same time? And allow me to host my own games online. Help would be VERY appreciated.
