Advanced MAC Filtering Page
This page allows you to define up to twenty Media Access Control (MAC) address filters
to prevent PCs 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.
