This solution is only partially effective because Comcast's Sandvine deployment sends a farced RST packet to both sides of the connection. The solution linked below drops the RST packet on your firewall keeping the connection from being torn down as far as your client is concerned, but it is not very likely that the other end will have this as well. This is not to say it can't help. Using HTTPS on the tracker and data encryption also help. So does any kind of tunneling including tor or DNS/icmp tunneling, but these have some level of performance impact that may be undesirable. -Scott _____ From: owner-nanog () merit edu [mailto:owner-nanog () merit edu] On Behalf Of Clinton Popovich Sent: Friday, October 19, 2007 4:49 PM To: 'Mark Owen'; 'Mike Lewinski' Cc: nanog () nanog org Subject: RE: Comcast blocking p2p uploads For anyone who is not aware this Comcast issue does have a solutions and its called iptables. works great for those behind either the great firewall of china or the great firewall of Comcast. http://redhatcat.blogspot.com/2007/09/beating-sandvine-with-linux-iptables .html Clinton Popovich Systems Administrator Nauticom Internet Services - An NPSI Company 2591 Wexford-Bayne Road, Suite 400 Sewickley, PA 15143 Tel: 724-933-9540 Fax: 724-933-9888 Email: crpopovi () nauticom net Web: <http://www.nauticom.net/> http://www.nauticom.net
