[cobalt-users] XTR Ipchains and port-forwarding

[Josh Kuperman <josh@xxxxxxxxxxxxxxxxxx>]

I believe some of what I'm asking is easy and some impossible.

In setting up ipchains and my dual ethernet xtr lets say I have :

eth0 on 1.2.4.0 network out on the internet with properly assigned ip
addresses from my ISP includ 1.2.4.2 through 1.2.4.4. I want the raq
itself to use 1.2.4.2 and 1.2.4.3. I want all 1.2.4.4 packets forwarded to
192.168.1.4; for the services I run on that machine - say web and telnet.
 
I want all packets for 1.2.4.2 to be handled by that machine. I want
packets going out from 192.168.1.100, my users on the private network
to be masqueraded by 1.2.4.2. 

The 1.2.4.3 address is mostly a test web server - but is running on
the RaQ. I'd like web and database to be handled, but telnet and mail
to be forwared to 192.168.1.3.

I downloaded the ipchains how-to and I think I can figure some of this
out by myself. I'm a little new to using ipchains for port-forwarding
outside connections comming in and need help there. Also, the RaQ XTR
is the first time I have one machine handling all my outsdie IP
addresses so I need some pointers there.
