Setting Up A Default DMZ Server
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The modem 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 computer can run the application properly if that
computer’s IP address is entered as the Default DMZ Server.
Incoming traffic from the Internet is normally discarded by the modem router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports 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.
How to Configure a Default DMZ Server
To assign a computer or server to be a Default DMZ server, follow these steps:
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
User Name of admin, default password of password, or using whatever Password and LAN
address you have chosen for the modem router.
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.
