This seems to be a growing problem as ISPs are having to answer to copyright holders for any infringement on their networks.
A good chunk of the DMCA requests we see are due to Bit Torrent.
While there is no singular way to block this protocol, I am very interested to hear what you have done on your network via your rv-series router to block torrenting activity.
