DMZ (Demilitarized Zone)
If you have a client PC that cannot run an Internet application
properly from behind the firewall, then you can open the client up
to unrestricted two-way Internet access. Enter the IP address of a
DMZ host to this screen. Adding a client to the DMZ (Demilitarized
Zone) may expose your local network to a variety of security risks,
so only use this option as a last resort.
