MAC Filtering
MAC filtering allows you to define up to twenty Media Access Control (MAC) address filters to prevent
computers from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This is useful
because the MAC address of a specific NIC card never changes, unlike its IP address, which can be
assigned via the DHCP server or hard-coded to various addresses over time.
