Thanks for the help Grandpa! That last article you linked to explains why I have two of those routers, one extra just in case I want to turn them into a bridge.

I'm pretty sure I did port forwarding correctly, but if I messed it up I think turning off the firewall and using DMZ would work. I did get the static IP set, and I checked the computer using ipconfig to make sure it really was using that address.

Thanks for checking the modem. I didn't think it had one, but I can't figure where else the block is. The connection goes from the modem to the router to a switch to my computer. Pretty sure there's no firewall in the switch. |^)

I have a feeling the problem is something on the computer. I never got azureus to work properly either, and that's a java based app. It has NAT problems no matter what I do and I am stuck with yellow smileys. My housemate is going through the same router and he has no problems.

It could be something arcane a virus messed up. The system is totally clean now, but it has had some adware attacks since the last wipe. It can't be anything too serious though since the computer works perfectly in every other respect.

Again thanks for the help. If anyone has suggestions for things I can try short of a format and reinstall I would love to hear them!
