DMZ Hosting
Selecting DMZ Hosting in the “Advanced Settings” 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 Modem’s network. 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 “Advanced Settings” screen generates the “Firewall
Security Level” screen. Select the level of security needed for the network. See
Appendix F for details concerning each level of security.
