N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition User Manual Setting Up a Default DMZ Server The default demilitarized zone (DMZ) server feature is helpful when you use some online games and videoconferencing applications that are incompatible with NAT. The wireless modem 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, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network. Incoming traffic from the Internet is usually discarded by the wireless modem 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 main menu, under Advanced, select WAN Setup. 2. Select the Default DMZ Server check box. 3. Type the IP address for that server. 4. Click Apply to save your changes. 76 | Chapter 6. Advanced Configuration

Setting Up a Default DMZ Server
The default demilitarized zone (DMZ) server feature is helpful when you use some online
games and videoconferencing applications that are incompatible with NAT. The wireless
modem 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, and is exposed to
many exploits from the Internet. If compromised, the computer can
be used to attack your network.
Incoming traffic from the Internet is usually discarded by the wireless modem 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 main menu, under Advanced, select WAN Setup.
2.
Select the
Default DMZ Server
check box.
3.
Type the IP address for that server.
