Default DMZ Server
The default demilitarized zone (DMZ) server feature is helpful when you use online games
and video conferencing applications that are incompatible with NAT. The router is
programmed to recognize some of these applications and to work correctly with them, but
there are other applications that might not function well. In some cases, one local computer
can run the application correctly if that computer’s IP address is entered as the default DMZ
server.
Note: For security reasons, 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. If compromised over
the Internet, the computer can be used to attack your network.
Incoming traffic from the Internet is usually discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports
screen. Instead of discarding this traffic, you can have it forwarded to one computer on your
network. This computer is called the default DMZ server.
To assign a computer or server to be a default DMZ server:
1.
In the WAN Setup screen, select the Default DMZ Server check box. The following
screen displays:
2. Type the IP address for that server and click Apply.
