Actiontec Wireless-Ready DSL Gateway User Manual
DMZ hosting is used to support online gaming and Internet conferencing services.
These programs usually require multiple open ports, making the network accessi-
ble 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.
