Firewall + NAT

["CHAN Chow Chin, David" <ccchan my ncs-i com>]

Hey Leonard den Ottolander and Karl L.Pearson,

	Sorry for disturbing.. I was wondering if you can give
me some pointers on how to configure a Linux box as a firewall???
I've read docs on IPMASQ, IPCHAINS and IPROUTE2 but I 
didn't find anything on what I am looking for. 

Basically, what I want it to do is to take over the router's NAT job. 
I am hoping that I can set it up together with ipfiltering. 
My problem is, in the Cisco router, you can nat a range of internal IPs
to a range of external ips. I am really stumped. I really can't find
any docs that I have read about exactly how to implement this.
Can you guys help me out?


Clueless,
David Chan
