Need to block network users from being able to access BitTorrent (BMTORRENT). I have a Sonicwall TZ-215 along with the premium content filtering. I can block the URL of the usage, but can not determined the proper ports to target the service to block.
Goal is to not have to upgrade to the "Application Control" that can detect the signature of the traffic or such. I am fine with blocking the defaults or making more difficult for the person. I understand that they could use other methods to avoid detection.
