Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and videoconferencing
applications that are incompatible with Network Address Translation (NAT). The modem router is programmed
to recognize some of these applications and to work correctly with them, but other applications might not
function well. In some cases, one local computer can run the application correctly if the IP address for that
computer is entered as the default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall and is exposed to exploits
from the Internet. If compromised, the DMZ server computer can be used to
attack other computers on your network.
The modem router usually detects and discards incoming traffic from the Internet that is not a response to
one of your local computers or a service or application for which you set up a port forwarding or port triggering
rule. Instead of discarding this traffic, you can direct the modem router to forward the traffic to one computer
on your network. This computer is called the default DMZ server.
To set up a default DMZ server:
1.
Launch a web browser from a WiFi-enabled computer or mobile device device that is connected to the
network.
2.
Enter http://www.routerlogin.net.
A login window opens.
3.
Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and password are
case-sensitive.
The BASIC Home page displays.
4.
Select ADVANCED > Setup > WAN Setup.
The WAN Setup page displays.
5.
Select the Default DMZ Server check box.
6.
Enter the IP address of the server.
7.
Click the Apply button.
