[SGVLUG] comcast hates U BitTorrent users

I am definitely NOT a iptables expert, but I think what you are doing is
telling the machine to reject TCP packets with the RST flag on the port
you tell your bit torrent client to use. Can any people with more
experience/knowledge let us know if this is a good idea? I am seeing
maybe legitimate RST messages getting discarded?
