Chapter 6 Advanced Setup
In this screen, the user can allow only certain IP addresses to access forwarded
ports. Enter the port range of the forwarded ports in the “Remote IP Port
Range” text boxes, enter the IP address to be allowed access in the “Remote
IP Address” text box, then click “Add.” The active forwarded ports will appear in
the “List of Forwarded Ports” text box.
To deactivate a forwarded port, select it from the “List of Forwarded Ports” text
box, then click “Remove.”
DMZ Hosting
Selecting DMZ Hosting in the “Advanced Configuration” 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 Gateway’s network. Access to the network resources while DMZ
hosting 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.
