Set Up MAC Address 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.

To configure MAC Address filters:

1. From any gateway Web Manager screen, click the Wireless 2.4 GHz or Wireless 5 GHz

main menu button on the gateway Web Manager menu bar.

2. Click MAC ADDRESS CONTROL from the Wireless submenu options list to display the MAC

Address Control screen.

3. Select the MAC Address Filter Type from the drop-down list:

None: Allows all Wi-Fi devices to connect.

Whitelist: Allows only listed Wi-Fi devices to connect.

Blacklist: Allows only Wi-Fi devices that are not listed to connect.

4. Click Add to enter the MAC Address of the client device that you want to block access to

your home network.
