Assign both ip addresses to the same interface. Set up a second interface
for the internal(home) inside.. other computers accessing the internet.. to
use the second interface as the default gateway. Then the firewall is easily
setup for firewall use. The best usae to put the two ips to is to use them
in a nat pool for routable returns.

Subject: 2nd external ip by dhcp question



Hello,

Our cable provder supplies two dhcp ips in their standard non-commercial
service.  I'm using Smoothwall and I'm very happy with it, but it is too
difficult for me to figure out how  set it up to get it to accept a second
external ip.

Does anyone know of a nice gui for iptable based firewalls that can setup
and manage two external ips?

I know how to add external eth0:1 eth0:2 ... interfaces and how to
port-forward through them using simple iptable rules, but I don't know how
to firewall each of these interfaces individually.

I've looked at guarddog and firestarter, but I don't see how these two
manage more than one external ip.

Thanks for any info,

Jim
