2.5 Firewall
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).
Parameters
Description
2.5.1 Port Filtering
Entries in this table are used to restrict certain types of data
packets from your local network to Internet through the Gateway.
2.5.2 IP Filtering
IP Filtering allows you to specify which IP can or can not be used
to access to internet.
2.5.3 MAC Filtering

can not be used to access to internet.

You can have different services (e.g. email, FTP, Web etc.)

Forwarding allows you to re-direct a particular range of service

IP address.

your WAN port IP address to a particular IP address in your LAN.
