DreadWingKnight Posted June 15, 2010 Report Share Posted June 15, 2010 Unfortunately, it is EXTREMELY difficult to block torrents without advanced packet monitoring software.Bittorrent isn't a network in the way that edonkey/emule or limewire are. It's a lot more difficult to block when you can't just block the normal boostrappers. Link to comment Share on other sites More sharing options...

DreadWingKnight Posted June 15, 2010 Report Share Posted June 15, 2010 ISA MIGHT let you restrict, but the rules required would need you to force all traffic through it and block all others. Link to comment Share on other sites More sharing options...
ehsanonlineco Posted June 15, 2010 Author Report Share Posted June 15, 2010 Cant I use a white list of TCP and UDP ports and just let the needed port be open ? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted June 15, 2010 Report Share Posted June 15, 2010 considering that torrent clients can (and have) used any port to listen on, pure port-based rules won't work. Link to comment Share on other sites More sharing options...

Switeck Posted June 16, 2010 Report Share Posted June 16, 2010 uTorrent uses random outgoing (ephemeral) ports, the same identical ones used by web browsers...so block one, block both! Link to comment Share on other sites More sharing options...

Switeck Posted June 18, 2010 Report Share Posted June 18, 2010 Usually, someone creating 100+ connections at once is using file sharing of some kind. Link to comment Share on other sites More sharing options...

Switeck Posted June 18, 2010 Report Share Posted June 18, 2010 If you cannot monitor traffic going through your sever, you are completely and thoroughly screwed. Link to comment Share on other sites More sharing options...

Greg Hazel Posted June 27, 2010 Report Share Posted June 27, 2010 It's worth noting that your data center has not filtered torrent traffic, but is asking you to stop it. This implies they are not capable of it either.So, you should pass along the same restrictions your data center is passing you. Tell your users to stop using BitTorrent. If they do not, disconnect them the same way you would be disconnected. If your data center says they have not stopped, ask how they can tell. Use that same method of detection to look at your users.
