Layer 2 Isolation
22.1 Overview
Layer-2 isolation is used to prevent connected devices from communicating with each other in the
UAG’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 UAG’s interface lan2. A printer, PC and
AP are connected to lan2. The IP address of the 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.
