Using the Configuration Menu
Advanced > DMZ
If you have a client PC that cannot run Internet applications properly from behind the
DI-774, 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.
