Layer 2 Isolation; Chapter 17 Layer 2 Isolation; Overview; What You Can Do In This Chapter - ZyXEL Communications ZyWall ATP series User Manual

17.1 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.
