To Block BitTorrent and P2P on a BEC router.

Login to the BEC router by opening a browser and in the address bar type: http://192.168.1.254

From Firewall go to IM/P2P Blocking.

In the Peer to Peer Blocking drop-down box, change the setting from "Disabled" to "Always On".
Also check the box that says "Block" in the BitTorrent Client field.

Choose Apply and then Save Configuration after it is done applying the changes.
