P2P L7 Script

RouterOS Beginner Basics

I am new to MT and need help to block Gnutella. I am using V3.0rc13. I have the regexp scripts but can someone give a quick example what I need to do with the script.

Regards
Paul

I’m not sure how you can block it with L7, but you can certainly block it through ip > firewall > Filter Rules “add chain=forward action=drop p2p=gnutella”

Thanks for your reply. I have done exactly that but limewire still can connect and download. It is not the encrypted version so I presume it should work but it does not .

Any ideas

I had same problem with Limewire, our customer using this P2P software to download music, etc and it slow down our internet speed.

ip firewall filter print
3 chain=forward action=drop p2p=all-p2p

4 chain=forward action=drop layer7-protocol=gnutella

The gnutella on Layer 7 Protocol:
^(gnd[\x01\x02]?.?.?\x01|gnutella connect/[012].[0-9]\x0d\x0a|get /uri-res/n2r?urn:sha1:|get /.user-agent: (gtk-gnutella|bearshare|mactella|gnucleus|gnotella|limewire|imesh)|get /.content-type: application/x-gnutella-packets|giv [0-9]:[0-9a-f]/|queue [0-9a-f]* [1-9][0-9]?[0-9]?.[1-9][0-9]?[0-9]?.[1-9][0-9]?[0-9]?.[1-9][0-9]?[0-9]?:[1-9][0-9]?[0-9]?[0-9]?|gnutella.*content-type: application/x-gnutella|…?lime)

I use mikrotik 3.2 DOM license
