Configuring MAC Address Filtering
MAC address filtering allows you to block traffic coming from certain known
machines or devices. The router uses the MAC address of a computer or device
on the network to identify it and block or permit the access. Traffic coming in from
a specified MAC address will be filtered depending upon the policy.
