Edit IP-MAC mapping list. Click on "Edit IP-MAC mapping list" to enter into IP-MAC binding page. To add a new IP-MAC address mapping list, enter the IP address and MAC Address accordingly on the top section. Then click the "Add" button to add it into the list below.

Note that if the entry of IP-MAC address mapping list already exists, the Router will ignore the new add-in. If the IP address is already entered, the Router will replace it with the new MAC address.
