DMZ Hosting
Selecting
DMZ
Hosting in the “Advanced Configuration” screen generates the
“
DMZ
Hosting” screen. To use
DMZ
hosting, enter the
IP
address of the computer
on the network to be used as a
DMZ
host in the “
DMZ
Host
IP
Address” text box,
then click On .
DMZ
hosting is used to support online gaming and Internet conferencing services.
These programs usually require multiple open ports, making the network acces-
sible from the Internet.
DMZ
hosting symbolically places the
DMZ
host computer
outside of the Router’s network. Access to the network resources while
DMZ
host-
ing is active is blocked. Action tec recommends activating
DMZ
hosting only as long
as necessary.
M
Warning : The
DMZ
Host computer will be vulnerable to com-
puter hackers on the Internet while in
DMZ
mode.
