Actually, as a Charter Cable customer in Pasadena, CA, all of my traffic from my streaming audio server was eventually blocked, regardless of which port(s) I chose. I'm guessing they're blocking home servers using some sort of packet sniffing to enforce this from their site: http://www.charter.com/customers/support.aspx?SupportArticleID=59 "No. Hosting Web servers, file servers, etc. using our residential services is not allowed due to the high outgoing-traffic volume likely from your computer to the Internet. If you require hosting capabilities, contact Charter and ask about our Charter Business Internet services, which may meet your needs."
