Chapter 6 Configuring Advanced Settings

DMZ Hosting

Selecting DMZ Hosting in the Advanced Setup tab 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 Modem’s network. Actiontec recommends activating DMZ hosting

only as long as necessary.

Warning: The DMZ host computer will be vulnerable to com-

puter hackers on the Internet while in DMZ mode.

Firewall

Selecting Firewall in the Advanced Setup tab generates the “Firewall Settings”

screen. Select the level of security needed for the network. See Appendix F on page

87 for details concerning each level of security.
