15 Firewall Settings

The Broadband router provides extensive firewall protection by restricting

connection parameters, thus limiting the risk of hacker attacks, 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

- Demilitarized Zone (DMZ)

If you have a client PC that cannot run an Internet application (e.g. Games)

properly from behind the NAT firewall, then you can open up the firewall

restrictions 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.
