Setting Up a Default DMZ Server
The default demilitarized zone (DMZ) server feature is helpful when you use 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 correctly with them, but there
are other applications 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.
