Considering the characteristics of BT download: the more people download, the faster the speed; The more seeds, the faster the speed. Only the most popular BT websites will have more people downloading Torrent files. Therefore, for the most popular BT websites and Tracker servers, configuring URL filtering rules based on "*bt*" wildcard on RG-WALL firewall can prohibit access to these websites and Tracker servers.
2. Enable traffic shaping to limit bandwidth or sessions.
BT has an impact on the network, because it occupies a lot of network exit bandwidth. Therefore, limiting the network bandwidth used by each user can reduce the harm of BT to the network. At the same time, it is unreasonable for operators to completely ban BT, and limiting the bandwidth of each BT is a better choice.
In addition, you can limit the number of sessions per user. We know that, generally speaking, about 50 sessions per user is enough for daily applications. Therefore, enabling the session restriction function of RG-WALL firewall can also effectively reduce the impact of BT application on network bandwidth.
3. Use "BitTorrent" feature library to detect
We know that no matter what kind of BT application, its software kernel is still based on BitTorrent protocol, that is to say, in the data stream of BT application, we can find that there is a BitTorrent protocol field in the load part of BT application data packet by intercepting the data packet. RG-IPS intrusion prevention system has the function of deep packet detection, which can identify the load part of the packet. Obviously, it is easy to block or restrict BT applications (even P2P applications) through IPS.
