Default DMZ Server
The default DMZ server feature is helpful when you use 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 function
correctly with them, but other applications exist that 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.
