Set the MAC Address for LAN port:

In a complex network topology with all the ARP bound devices, if you want to change to use TL-ER6120 instead of the current router in a network node, you can just set the MAC address of TL-ER6120 ‘s LAN port the same to the MAC address of the previous router, which can avoid all the devices under this network node to update their ARP binding tables.

Set the MAC Address for WAN port:

In the condition that your ISP has bound the account and the MAC address of the dial-up device, if you want to change the dial-up device to be TL-ER6120, you can just set the MAC address of TL-ER6120’s WAN port the same to the MAC address of the previous dial-up device for a normal Internet connection.

Set the MAC Address for DMZ port:

The application of MAC address for DMZ port is similar to that for LAN port.
