How do I forward ports on a Comcast SMC 8014 w/ a static IP? (Doesn't seem to work?)

How do I forward ports on a Comcast SMC 8014 w/ a static IP? (Doesn't seem to work?) I'm trying to set up port forwarding with my Comcast cable modem, an SMC 8014. Normally this is pretty straightforward (give a port range, tell it to forward to a LAN IP) but for some reason it doesn't seem to be passing traffic through on this box. :(

"It sounds like the SMC 8014 does not know how to route the packets back to you. Port forwarding on basic routers normally only forwards traffic from a WAN IP address to LAN IP address. I think in this case, because you are trying to connect from a LAN IP address to a WAN IP address, the data is lost because the router does not have any LAN to WAN port forwarding rules set up. Only WAN to LAN. Some routers are clever and do not have this problem.

It would be worth asking someone to test the WAN IP address to see if they can connect. I checked the setup on portforward.com and I cannot see any other settings that need to be changed on the router, beyond what you have done.

Ah ha.. I'm not going completely crazy. There is a post on this exact problem here on superuser which explains it much better than I can."

There should be a setting called "DMZ", just input your static ip and then check the enable box. All of your ports should be forwarded.
