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.
