Setting Up A Default DMZ Host

The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The gateway is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC's IP address
is entered as the Default DMZ Host.
Note: For security, you should avoid using the Default DMZ Server feature. When a
computer is designated as the Default DMZ Server, it loses much of the protection of the
firewall, and is exposed to many exploits from the Internet. If compromised, the
computer can be used to attack your network.
Incoming traffic from the Internet is normally discarded by the gateway unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding or Port Triggering menu. Instead of discarding this traffic, you can have it forwarded
to one computer on your network. This computer is called the Default DMZ Host.
To assign a computer or server to be a DMZ Host, from the Main Menu, under Advanced, select
DMZ Host. Enter the IP address of the computer you would like to assign as a DMZ Host and click
Apply. To disable the DMZ Host, enter "0" and click Apply.
