There's really no magic to it. Basiclly, if there's a "port" opened through
the firewall then people will slip out and things can slip in. I do not know
the workings of Napster. Does it work behind firewalls?
One thing firewalls can do is "remember" who requested what information, so
that the packets which come streaming back to it can find their target
(otherwise they would be useless). Several (behind firewall applications) I
know use port 80 (the 'web port' or http traditionally). This port is very
commonly open on firewalls so that users can "get out" to the web. The
firewall still has to maintain the rerouting of the packets back to the
internal user, however (in effect).
Some programs will allow you to put your own port number in it for proxie
servers etc. It's simply up to the Firewall setup. However, users who
request info from behind the firewall STILL appear with the firewall's IP.
There's no magical way around that. Not to mention the IP they are assigned
behind the firewall would be useless to you.
