Applications and Gaming > DMZ
The DMZ feature allows one network computer to be
exposed to the Internet for use of a special-purpose
service such as Internet gaming or videoconferencing.
DMZ hosting forwards all the ports at the same time to
one PC. The Port Range Forward feature is more secure
because it only opens the ports you want to have opened,
while DMZ hosting opens all the ports of one computer,
exposing the computer to the Internet.
Applications and Gaming > DMZ
DMZ

address assigned to it because its IP address may change
when using the DHCP function.
To expose one PC, select

computer’s IP address in the DMZ Host IP Address field. This
feature is disabled by default.
