Dear Kerio firewall professionnals,

I'm trying to limit minimum of bittorent usage since they now use encryption so low level packet filtering is now useless.

I want to block .torrent file from being downloaded off the web.

some website link like this http://www.example.com/file/test.torrent

so a basic URL rules can apply but IF they use a redirector script which is 90% of the torrent website like this : http://www.example.com/getfile.php?id=75747548

The url filter cannot be applied in this case.


How i can block effectively .torrent file?


Thank you for your support!

Laurent

You are right the HTTP filter does not currently recognize this. However you can filter the torrent file mime type (application/x-bittorrent) which should work for most sites.

1.) define "Definitions -> URL Groups" a new Group "Forbid Torrent" with *.torrent in URL

2.) create "Content Filter -> HTTP Policy" a new policy to block traffic for your new generated URL Group "Forbid Torrent"


The User CAN access your example URL

http://www.example.com/getfile.php?id=75747548

.... but not the resulting URL xxx.yyy.zzz.file.torrent.

I have used this against downloading all "fun - files" like .wma/.mov/.mp4 and and and


Regards
Uwe

why don't you block torrents in traffic rules ???
allow only following common ports for routine task, http, https, dns, pop3, smtp, ftp etc,
and create a separate rule for torrents, add allowed user to source,
