DMZ Server

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 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.
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 Server.
The Security menu, shown in
Figure 6-2. Security menu.
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
gateway, and is exposed to many exploits from the Internet. If compromised, the
computer can be used to attack your network.
To assign a computer or server to be a Default DMZ server:
Click Default DMZ Server.
1.
Type the IP address for that server.
