MAC address
A   MAC   address   assigned   to   the   interface.   This   parameter   is
mandatory if your ISP uses MAC address binding. In the field, enter
the   MAC   address   registered   by   your   ISP   upon   concluding   the
agreement.

computer that is being used to configure the router at the moment)
as the MAC address of the WAN interface, move the Clone MAC

moved to the right, the field is unavailable for editing.
To set the router's MAC address, click the RESTORE DEFAULT

moved to the right).
