M0n0wall is a freebsd based system but it does support a public IP DMZ/Service interface. You have to enable advanced NATing.
Layer-3/4 Source and Destination NAT/PAT (network/port address translation) is _not_ the same as layer-2 bridging or layer-3 routing between networks and inspecting the packets then. I think he's looking for layer-2 bridging or layer-3 routing, not SNAT/DNAT.
IPCop does SNAT/DNAT, and can translate multiple public IPs into private ones -- LAN, 2nd LAN (e.g., WLAN), DMZ, etc... as well. 1:1 (NAT-only), 1:Many, Many:1. Not the same as inspecting frames/packets as they pass through a true layer-2 bridge, or a layer-3 router.
Remote updating of the firmware/software is a big plus too.
As with IPCop.
