However, I recommend that you don't actually block it, just give it a VERY low bandwidth. That way the users do not waste time trying to get round the problem, but it is very frustrating and they actually stop using it. Done this successfully at a couple of schools, and the stats show almost no P2P activity after a short while.</P></BODY></HTML> Tue, 01 Apr 2008 10:33:47 GMT https://community.cisco.com/t5/network-security/blocking-p2p/m-p/958735#M940038 i-kendall 2008-04-01T10:33:47Z Re: Blocking P2P https://community.cisco.com/t5/network-security/blocking-p2p/m-p/958736#M940039 <HTML><HEAD></HEAD><BODY><P>throttle down the bandwidth with rate limting CAR?
