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 the network to block specific machines from accessing 

your LAN.

To filter a specific MAC address, enter the MAC address in the blank provided then press Add.

The format of MAC address-- could be: xx:xx:xx:xx:xx:xx or xx-xx-xx-xx-xx-xx
