CHAPTER 23

Private LAN

This chapter shows you how to set up a private LAN that allows specified devices to communicate with each other.

23.1 Private LAN Overview

By default the IP Plug and Play (iPnP) and layer-2 isolation features (see Section 5.1 on page 56) are enabled to prevent devices on the LAN from communicating with each other. These features provide additional security protection.

However, you can configure a private LAN to allow communication between devices with the specified IP addresses in the Private LAN screen. The VSG does not apply iPnP or layer-2 isolation on the devices in a private LAN.

The following figure shows a network example where computers A and B can communicate with each other in the private LAN. Since computers C and D are not in the private LAN, the VSG disallows communication between the two.
