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.
