There should only be a gateway assigned to the public NIC that is
attached to the internet. The internal NIC and the DMZ NIC should have
no gateway. You then should add static routes for your DMZ.

I have a DMZ, and the NICs on the ISA firewall are,
192.168.1.1:255.255.255.0, (Internal), 63.71.109.4:255.255.255.248,
(External-dirtynet), and 63.71.109.107:255.255.255.0(DMZ segment), for
some reason the 107 works fine on .0, on an ip standpoint does that look
right, what should my gateway be on my dmz computer NIC.   Is this
configuration even correct.  I have looked at the learning zone but
still this does not work.  When I enable the dmz nic the internal
network computers can not get to the internet.  I have the
External-dirtynet on a separate hub as well as the dmz network and
internal.  Do I need to put a specific route in a host file or in
routing and remote access.  If so what would be the correct route?
Thanks in advance.
