This chapter describes how to configure LAN settings. This chapter is only applicable when the ZyWALL is in router mode.

6.1 LAN, WAN and the ZyWALL

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 8 on page 151 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.

6.2 IP Address and Subnet Mask

Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number.
