natd doesn't care whether you use routable or non-routable IPs; you can NAT an
external IP, too, if you really want to.
But if you simply want to set up a small DMZ where the hosts are not doing NAT
but just using routable IP's, that's trivial: set gateway_enable in
/etc/rc.conf, and away you go. In this case, you'd want three interfaces on
the box, a WAN, a LAN, and a DMZ, preferably all on distinct subnets.
