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.
