Michael: I would test dropping the traffic. I say this because there were cases where we thought we were rate shaping because connections were showing up in the table - however not all appropriate connections were rate limited. There are nuances between different client side applications for the P2P apps such as bittorrent.exe and utorrent.exe. This causes different network traffic patterns. Some of these P2P apps are very ingenious at establishing connections to peers. If you can block it successfully, you should be able to rate limit it. It seems that the file transfers are over TCP and some support TLS. Let us know how it works, I am sure others are interested too. -Alex -----Original Message----- From: Michael Lymbery [mailto:mlymbery () SCU EDU AU] Sent: Wednesday, October 03, 2007 7:30 PM To: SECURITY () LISTSERV EDUCAUSE EDU Subject: Re: [SECURITY] Limewire 4.14 We are currently trialling a Packetlogic from Netintact and I just tried Limewire 4.14 through it. It was correctly classified as Gnutella so now I can block or shape it. Alex Everett wrote:

Our Firewall has an option to block Gnutella networks which used to do the trick. However not with version 4.14.
