Chapter 4 Using Advanced Setup
In this screen, the user can create a custom set of rules for a game or applica-
tion not listed in the Application Level Gateway screen. Enter the “Rule Name,”
“Protocol,” “Port Start,” “Port End,” and “Port Map” in the appropriate text boxes,
then click Apply. The rules are summarized at the bottom of the screen, and the
rule set will appear in the Application Level Gateway screen after clicking Back.
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. 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.
