Mobile Broadband 11n Wireless Router MBR1210 User Manual Setting Up a Default DMZ Server WARNING! 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. The default DMZ server feature is helpful when you are 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 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. 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 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. Go to the WAN Setup screen as described in the previous section. 2. Select the Default DMZ Server check box. 3. Type the IP address for that server. 4. Click Apply to save your changes. Chapter 5. Advanced | 67

Setting Up a Default DMZ Server
WARNING!
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.
The default DMZ server feature is helpful when you are 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 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.
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 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.
