Chapter 8 Firewall Settings
The Broadband router provides extensive firewall protection by restricting connection
parameters, thus limiting the risk of hacker attack, and defending against a wide array of
common Internet attacks. However, for applications that require unrestricted access to the
Internet, you can configure a specific client/server as a Demilitarized Zone (DMZ).
Note: To enable the Firewall settings select Enable and click Apply
8.1 DMZ
If you have a local client PC that cannot run an Internet application (e.g. Games) properly
from behind the NAT firewall, then you can open the client up to unrestricted two-way
Internet access by defining a DMZ Host. The DMZ function allows you to re-direct all packets
going to your WAN port IP address to a particular IP address in your LAN. The difference
between the virtual server and the DMZ function is that the virtual server re-directs a
particular service/Internet application (e.g. FTP, websites) to a particular LAN client/server,
whereas DMZ re-directs all packets (regardless of services) going to your WAN IP address to
a particular LAN client/server.
Parameters Description
Enable DMZ Enable/disable DMZ
Note: If there is a conflict between the Virtual Server and the DMZ setting, then Virtual
Server function will have priority over the DMZ function.
