routing problem

[awal]

i am trying to setup my network and cant seem to figure out what the best way to do it is. here is my current setup

--------------
| internet |
--------------
|
|
====================
| linux firewall |
====================
|
|
|
---------------------------
| |
| internal machines |
| |
---------------------------

this configuration has been working for the past 2 yrs, with no problems. the linux firewall has one public and one private IP.

what i would like to do know is add another machine to this setup, but have it have a public IP and still be behind the linux firewall. i am trying to make the linux box do both masquerading and routing, but i am unsure how to even approcah this. any ideas, or pointers? below is this ascii art.

you could just bind the new IP to the linux firewall and forward *everything* going to that new ip towards one ip on the intranet ...

still behind the firewall, full access.

how would i forward all ips to an internal machine? is there one command that will do this? i am using iptables...
