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.
