Firewall rules can be used to allow or deny traffic passing through the router. You can specify a single port by utilizing the input box at the top or
a range of ports by utilizing both input boxes. DMZ means "Demilitarized Zone". DMZ allows computers behind the router firewall to be accessible
to Internet traffic. Typically, your DMZ would contain Web servers, FTP servers and others.
The following parameters will be available for configuration:
Enable DMZ: Tick this option to enable the DMZ feature.
DMZ IP Address: Enter the IP address of the computer on the
LAN that you want to have unrestricted Internet
communication in the DMZ IP address field. To

Name drop-down to select the computer that you
want to make a DMZ host. If selecting a computer

not change.
