created and enabled, it will also display in Firewall Rules. Firewall Rules contains all

network firewall rules pertaining to IP (Internet Protocol).

In the Firewall Rules List at the bottom of the screen, the priorities of the rules are

Advanced > DMZ

Using the Configuration Menu

If you have a client PC that cannot run Internet applications properly from behind the

DI-764, then you can set the client up to unrestricted Internet access. It allows a

computer to be exposed to the Internet. This feature is useful for gaming purposes.

Enter the IP address of the internal computer that will be the DMZ host. 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.
