Thanks for the reply. I know I'm grasping at straws, but I can't find anything else on the forum to try. I did meticulously change everything to the same port, though, and tried several alternative ports. I did notice on the router setup some other settings that portforward.com didn't suggest changing, but I keep wondering if there is something I'm not changing, like changing the Internet Connection Type from Automatic Configuation - DHCP to Static IP or something.

The only other p2p software I have tried is xolox, but that has been a few years. I guess I could try another one just to see if it connects past the router. Any suggestions? I've seen a few mentioned here.
