5.3.4.2 MAC Filter

A MAC (Media Access Control) address is the unique network hardware identifier for each

PC on your network’s interface (i.e. its Network Interface Card or Ethernet card). Using your

router’s MAC Address Filter function, you can configure to block specific machines from

accessing your LAN.

There are no pre-defined MAC address filter rules; you can add the filter rules to meet your

requirements.

MAC Address: Enter the MAC addresses you wish to manage.

Time Schedule: It is self-defined time period. You may specify a time schedule for your

prioritization policy. For setup and detail, refer to Time Schedule section.

If the DHCP server option is enabled, you must be very careful in

assigning IP addresses of a filtered private IP range to avoid conflicts

because you do not know which PC in the LAN is assigned which IP

address. The easiest and safest way is that the filtered IP address is

assigned to a specific PC that is not allowed to access an outside resource

such as the Internet. You configure the filtered IP address manually for this

PC, but it stays in the same subnet with the router.
