2-6Firewall

The Broadband Router provides extensive firewall protection by restricting connection parameters to limit the risk of hacker attacks, and defending against a wide array of common hacker attacks.

The Broadband Router provides packet filtering rules by restricting service ports, IP address, or MAC address. However, for applications that require unrestricted access to the Internet, configure a specific client/server as a demilitarized zone (DMZ).
