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