DMZ Host
The DMZ (De-militarized Zone) Host page allows you to configure a network device (e.g.
a PC) to be exposed or visible directly to the Internet. This may be used if an application
doesn’t work with port triggers. If you have an application that won’t run 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 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 Host page:
1 Click the Router menu tab.
2 Then click the Advanced/DMZ Host submenu.
Figure 21 shows an example of the menu.
