[NTLUG:Discuss] Punch through firewall

[Jonathan Miller]

You can either use NAT (Network Address Translation) or Port
Forwarding. Since you've got the addresses I'd say go with NAT. That'll
allow you to say 200.200.200.201 -> 192.168.1.200. Port fowarding does
exactly like it sounds like it does i.e. 200.200.200.201:80 ->
192.168.1.200:80

Information for setting up NAT with 2.2 can be found
at: http://www.linuxdoc.org/HOWTO/Net-HOWTO-8.html. This is all going to
change (again!) with 2.4, but that's life.
