CHAPTER 7
LAN Screens
7.1 Overview
A network is a shared communication system to which many computers are attached.
The Local Area Network (LAN) includes the computers and networking devices in your home
or office that you connect to the ZyWALL’s LAN ports.
The Wide Area Network (WAN) is another network (most likely the Internet) that you connect
to the ZyWALL’s WAN port. See Chapter 9 on page 169 for how to use the WAN screens to
set up your WAN connection.
The LAN and the WAN are two separate networks. The ZyWALL controls the traffic that
goes between them. The following graphic gives an example.
