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.
