This chapter describes how to configure LAN settings. This chapter is only applicable when
the ZyWALL is in router mode. The LAN Port Roles screen is available on the ZyWALL 5
and ZyWALL 35.

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
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.
