Chapter 7 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
7.1 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.
