Blocking BitTorrent Traffic

Unanswered Question
Aug 7th, 2008


I have recently got a Cisco 877 Router for my company internet subscription. I would like to setup the router to block all BitTorrent traffic. Can you advise me how this can be done? Thanks.

I have this problem too.

do the following

class-map match-any sdm_p2p_kazaa

match protocol fasttrack

match protocol kazaa2

class-map match-any sdm_p2p_edonkey

match protocol edonkey

class-map match-any sdm_p2p_gnutella

match protocol gnutella

class-map match-any sdm_p2p_bittorrent

match protocol bittorrent

policy-map blocking_P2P

class sdm_p2p_gnutella


class sdm_p2p_bittorrent


class sdm_p2p_edonkey


class sdm_p2p_kazaa


the apply it in two directions on the outside interface

lets say

interface fa0/1

service-policy input blocking_P2P

service-policy output blocking_P2P

and should work perfect

good luck

My IOS does not understand fasttrack, kazaa2, edonkey, gnutella, and bittorent. My version of IOS is 12.4T(15). And my router is Cisco 877. I thought QoS is avaible, but seems like it does not. Anything that I need to do to enable it? Newbies with Cisco router. Many questions. Thanks.
