hello
does anyone know how napster is able to work from behind the firewall,
even though the firewall
doesn't permit any outbound tcp high-ports and also drops all traffic
initiated from outside?
if i am correct, by the laws of TCP/IP, the only thing coming back should
be on the same established connection,
and that would be governed by what you allow outbound on your firewall. i
don't permit any inbound traffic, and yet have users able to use napster.
the only ports i allow outbound are http/https. is it possible that
napster sets itself up such that it does its peer-to-peer file-sharing
through any available open port, in this case tcp/80 and 443?
any feedback would be appreciated!
rgds,
-k
