Hi @Rodnie, 
Greeting Forum, Please kindly enable IP/MAC Binding feature at interface where the IP/MAC from.

IP address to MAC address binding helps ensure that only the intended devices get to use privileged IP addresses

Suppose you configure access privileges for IP address 192.168.1.27 and assign it to Kevin'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.

Thank you

For Layer3 router, ZyXEL firewall doesn't support block client by MAC address(Layer 2). You can only block MAC address by swtich or by AP profile.

Or you can consider block client "IP traffic(Layer 3)" by current functions.
(1) Add MAC address into "Static DHCP Table" settings, and assign a specific IP address for client.
e.g. IP: 192.168.100.201, MAC: XX:XX:XX:XX:XX:XX
(2) Block IP address by policy control rule.
e.g. Source: 192.168.100.201, Destination: Any, Action: Deny.
