It's more than just having the port "open" on all of your networking gear. It's about having the traffic passed to your PC.

My recommendation is to go here: http://testmyports.com/pfexp.php and understand what it is exactly you are trying to do, which is probably port forwarding (because you have an internal IP address most likely).

If that's the case, go to http://portforward.com and find a forwarding guide for your equipment.

Then, when you think you've got everything set up as required, open your torrent client (which will open port 6881 on your PC), then go to http://testmyports.com to test it.
