Port Forwarding for BitTorrent on a computer on the network.?

I recently changed the port that my bit torrent uses and now i can't figure out how to forward a port for it. when i use portforward.com my browser will not let me put the router ip address in the address bar. it always comes up with internet can not connect or something like that. now my bit torrent is slow and is not working properlly. at the bottom i have the yellow triangle that says that i have no incoming connections. please help ASAP. thank you.
