Yep, if your internal network addresses are unregistered, the ISP won't
know to route traffic destined for your internal network through the PPP
link. Socks4 and Socks5 address this problem extremely well by mapping
connections to a port on the gateway. Thus, only outbound connections
(from your internal network to the outside) will work, and the only
inbound connections that can be made are to your gateway (FreeBSD box).
So if you want to telnet to your Irix box from the outside, you have to
telnet to your gateway first, then to the Irix box. Price ya pay for
unregistered IP's...
