You don't need to do this. You can run all the IPs on the firewall
box, and route them to machines on a private subnet behind the firewall.

I've had good results doing what you describe - but it's fairly slow
to get it up and running and the process is very detail oriented, and
you end up having to do quite a bit of spadework to get a config that
is as hardened and reliable as a commercial firewall product. There
are some reasonable graphical tools that can help you. The one I've
used is fwbuilder (http://www.fwbuilder.org/).
I've also looked at Vyatta, and heard good things about pfsense.
