I've put up a copy of my firewall setup script at:
   http://www.taupro.com/firewall

It runs under Red Hat 5.2 using ipchains (usually found in RH 6.0, I retrofitted
ipchains into 5.2 using an RPM of mine).  The script shows usage of
masquerading in two simultaneous cases --

1) My home LAN is 192.168.200.x and I dial into my ISP with a dynamic IP;
    hence everything in 192.168.200.x is masqueraded to the Internet

2) My employer's LAN is 10.x.x.x and I dial in there with a dynamic IP as
    well; using ISDN, I can be dialed into both places simultaneously and
    yet I have the masqueraded networks isolated from each other.

I don't run a server on the Internet, so the firewall is configured to reject
attempts to connect back into my site, but I do allow NetBIOS/SAMBA
stuff to flow to/from my LAN to my employer's site so I can share.

What kind of problems are you having?
