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
) 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.
