Chapter 6 LAN and WAN Setup

60

This chapter shows you how to configure the LAN and WAN ports on the VSG..

The Ethernet parameters of the VSG are preset to the following values:

1 WAN IP address of 192.168.1.1 with subnet mask of 255.255.255.0.

2 LAN IP address of 10.59.1.1.

3 DHCP server enabled on the LAN with a 252 client IP address pool starting from 

10.59.1.2

These parameters should work for the majority of installations. If you wish to change the 
factory defaults or to learn more about TCP/IP, please read on.

A LAN (Local Area Network) is a computer network limited to the immediate area, usually 
the same building or floor of a building. A WAN (Wide Area Network), on the other hand, is 
an outside connection to another network or the Internet.

A static IP is a fixed IP that you configure on the VSG. A dynamic IP is not fixed; the DHCP 
server provides an IP address to the VSG each time it connects to the network. When an 
Ethernet device is configured to obtain a dynamic IP address from a DHCP server, it is known 
as a DHCP client.

Like houses on a street that share a common street name, the computers on a LAN share one 
common network number.

Where you obtain your network number depends on your particular situation. If the ISP or 
your network administrator assigns you a block of registered IP addresses, follow their 
instructions in selecting the IP addresses and the subnet mask.
