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 cable 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 cable 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 that you configured
in the Port Forwarding/Port Triggering page. Instead of discarding this traffic, the cable
modem router can 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 computer or mobile device that is connected to the
cable modem router network.
2.
Enter http://routerlogin.net or http://192.168.0.1.
A login window opens.
3. Enter the cable modem router admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. 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. Type the IP address.
