IPTABLES Help

[fyrbrds at netscape.net]

 Most bittorrent clients are no longer using standard ports. Blocking it without knowing what port it will be on requires some sophisticated packet inspection. Comcast was using 3rd party software to do this and injecting session termination packets into the stream to disrupt the connections. I don't remember the name of this comcastic software but you can google it. This solution will not be cheap however so you have to really NEED to block it to be worth the cost. AFAIK, the only way you can do it is to have a white list of ports and/or client machines for your proxy to filter. This will have marginal success as I have busted this blockade myself on many occasions. Also, this approach won't stop bittorrent through tunneling which can pretty much get around anything you do as long as you have an open connection. Probably the best you can do is take the simple route like AT&T and impose draconian bandwidth limits.
