Tor needs distributed proxy repeaters. Do not attempt to configure unless you know what you're doing or have your work supervised by someone who does. A bad configuration can backfire on you (and the neighborhood you and your neighbors used to live in). http://www.torproject.org/docs/tor-doc-relay.html.en
