Layer 2 Isolation
28.1 Layer 2 Isolation Overview
Layer-2 isolation is used to prevent connected devices from communicating with each other in the Zyxel
Device’s local network(s), on which layer-2 isolation is enabled, except the devices in the white list.
Note: Layer-2 isolation does not check the wireless traffic.
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. 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.
