MAC Filter
MAC Filter Overview
You can configure the Zyxel Device to permit access to clients based on their MAC addresses in the MAC Filter screen. This applies to wired connections. Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. You need to know the MAC addresses of wired LAN client to configure this screen.
