Torrents and Torrent Trackers

Article author

Numerous businesses and organizations aspire to block Torrents due to the significant amount of bandwidth this type of traffic consumes, as well as its frequent use in downloading illegal or explicit content. However, given the nature of its operation, blocking torrent traffic is almost impossible. Torrenting applications aren't confined to a single port or protocol, rendering basic firewall rules ineffective. With the emergence of WebRTC, torrent traffic can even occur over HTTP.

There are a few strategies, however, that can significantly curb the activity and impact of torrenting:

  1. Restrict access to tracker sites that distribute .torrent files
  2. Implement a Layer-7 firewall capable of deep packet inspection
  3. Use Quality of Service (QoS) to throttle bandwidth-consuming endpoints

DNSFilter is adept at implementing the first solution on this list - restricting access to sites known to distribute .torrent files. You can conveniently accomplish this by blocking the P2P & Illegal category in your site policy. This prevents end users from accessing these sites and initiating torrent downloads from them.

Implementing firewall rules and Quality of Service rate limits can also deter users engaging in torrenting activity. There are multiple security vendors that offer physical or virtual firewall appliances capable of application-layer inspection and application-specific bandwidth limitation.
