LAN Devices
This chapter describes how you can remotely access devices on the LAN through the VSG.
21.1 LAN Devices Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a
host in a packet. Form example, the source address of an outgoing packet, used within one
network is changed to a different IP address known within another network.
Traditionally, when you have a device (for example, a switch) on a LAN using NAT, you
cannot access the device from the WAN since the LAN device is assigned a private IP address.
Your VSG is a NAT-enabled device that makes your whole inside network appear as a single
computer to the outside world.
21.1.1 Port Mapping
To make LAN devices behind the VSG visible to the outside world, you configure a mapping
between a virtual port on the VSG and a server port on a LAN device. A virtual port is a port
on the VSG that appears as a physical port to the attached devices. A server port defines a
server to which all specified requests are forwarded.
In addition, centralized LAN device management is possible through the VSG using port
mapping. You can access the management interface on the LAN device remotely provided that
the LAN device has allowed remote management.
