Configuring Your Gateway
Configuring DMZ Settings If you have a local client computer that cannot run an Internet application properly behind
the NAT firewall, you can configure it for unrestricted two-way Internet access by defining it
as a Virtual DMZ host. Adding a client to the Demilitarized Zone (DMZ) may expose your
local network to various security risks because the client is not protected, so use this option
as a last resort.
To access the DMZ (Demilitarized Zone) menu, click Firewall in the menu bar and then click
the DMZ submenu in the menu bar. Figure 35 shows an example of the menu.

1. In the DMZ (Demilitarized Zone) menu, check Enable DMZ Host. The 2 rightmost fields
next to this option become available.
2. Enter the last two octets in the public IP that is used as the DMZ host's public address.
3. Click Apply.
