Reference Manual for the Model MR814 Wireless Router
Advanced Configuration of the Router 8-5
DMZ Server
Incoming traffic from the Internet is normally 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 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 router 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 8-2, allows the configuration of a Default DMZ Server.
Figure 8-2. Security menu.
To assign a computer or server to be a Default DMZ server:
1. Click Default DMZ Server.
2. Type the IP address for that server.
3. Click Apply.
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
router, and is exposed to many exploits from the Internet. If compromised, the computer
can be used to attack your network.
