All other traffic is not allowed through the interface. The device allows traffic through the interface only if the source or destination IP address and MAC address matches an entry on the list. When you configure static MAC address binding, you can select the Only allow traffic sent from or to these MAC/IP addresses check box For information about MAC access control, see Restrict Network Traffic by MAC Address. This feature is similar to the MAC access control feature, except that static MAC address binding associates each MAC address with a specific IP address. You can also use this feature to block all network traffic to devices that match the MAC and IP addresses on this list. If this feature is enabled, a computer with a specified MAC address can send and receive information only if it uses the associated IP address. To use MAC address binding, you must configure the interface to associate a client IP address with a MAC address. This feature can protect your network from ARP poisoning attacks, in which hackers try to change the MAC address of their computers to match a real device on your network. You can control access to an interface on your Firebox by computer hardware (MAC) address.
