3.5 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
3.5.1 Port Filtering
Entries in this table are used to restrict certain types of data
packets from your local network to Internet through the Gateway.
3.5.2 IP Filtering
IP Filtering allows you to specify which IP can or can not be used
to access to internet.
3.5.3 MAC Filtering
MAC Filtering allows you to specify which MAC Address can or
can not be used to access to internet.
3.5.4 Port Forwarding
You can have different services (e.g. email, FTP, Web etc.)
going to different service servers/clients in your LAN. The Port
Forwarding allows you to re-direct a particular range of service
port numbers (from the Internet/WAN Ports) to a particular LAN
IP address.
3.5.5 DMZ
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.
