IP/MAC Binding
16.1 IP/MAC Binding Overview
IP address to MAC address binding helps ensure that only the intended devices get to use privileged IP
addresses. The Zyxel Device uses DHCP to assign IP addresses and records the MAC address it assigned
to each IP address. The Zyxel Device then checks incoming connection attempts against this list. A user
cannot manually assign another IP to his computer and use it to connect to the Zyxel Device.
Suppose you configure access privileges for IP address 192.168.1.27 and use static DHCP to assign it to
Tim’s computer’s MAC address of 12:34:56:78:90:AB. IP/MAC binding drops traffic from any computer
trying to use IP address 192.168.1.27 with another MAC address.

IP/MAC address bindings are based on the Zyxel Device’s dynamic and static DHCP entries.
