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. -- -Chuck
