Chapter 4 Using Advanced Setup
DMZ Hosting
Selecting
DMZ
Hosting in the “Configuring the Advanced Settings” screen gener-
ates 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 Modem’s network. Access to the network resources while
DMZ
host-
ing is active is blocked. Actiontec 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.
Firewall
Selecting Firewall in the “Configuring the Advanced Settings” screen generates the
“Firewall Security Level” screen. Select the level of security needed for the network.
See Appendix F on page
91
for details concerning each level of security.
