Layer 2 Isolation
18.1 Overview
Layer-2 isolation is used to prevent connected devices from communicating with each other in the Zyxel
Device’s local network(s), except for the devices in the white list, when layer-2 isolation is enabled on
the Zyxel Device and the local interface(s).
Note: The security policy control must be enabled before you can use layer-2 isolation.
In the following example, layer-2 isolation is enabled on the Zyxel Device’s interface Vlan1. A printer, PC
and AP are in the Vlan1. The IP address of network printer (
C
) is added to the white list. With this setting,
the connected AP then cannot communicate with the PC (
D
), but can access the network printer (
C
),
server (
B
), wireless client (
A
) and the Internet.
