Setting Up A Default DMZ Server
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The modem 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 computer can run the application properly if that
computer’s IP address is entered as the Default DMZ Server.
Incoming traffic from the Internet is normally discarded by the modem unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called 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, and is exposed to many exploits from the Internet. If
compromised, the computer can be used to attack your network.
