well I guess I don't have to worry about Limewire anymore but I still need to block bittorrent traffic for our clients using the RouterBOARD 750G. I want to totally block it and not rate-limit it. I have had success using Cisco's NBAR and I hope the Mikrotik will work as well.

I am trying:

5 ;;; P2P
chain=drop action=mark-connection new-connection-mark=P2P-CONN
passthrough=no p2p=all-p2p

6 ;;; P2P Torrent
chain=drop action=mark-connection new-connection-mark=P2P-CONN
passthrough=no layer7-protocol=bittorrent

But it does not seem to have any effect on the torrent traffic. Any ideas?

Thanks,

Fearon
