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 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 that computer’s IP address 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 router usually detect and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you have configured in the Port
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can forward it to one
computer on your network. This computer is called the default DMZ server.
To set up a default DMZ server:
1.

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets
travel through many devices along the way. If any device in the data path has a lower MTU
setting than the other devices, the data packets have to be split or “fragmented” to
accommodate the device with the smallest MTU.
