CHAPTER 5
LAN Setup
This chapter describes how to configure LAN settings.
5.1 LAN Overview
A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN is a computer network limited to the immediate area, usually the same
building or floor of a building. The LAN screens can help you configure a LAN DHCP server
and manage IP addresses.
5.1.1 LANs, WANs and the ZyXEL Device

WAN ports. There are two separate IP networks, one inside the LAN network and the other
outside the WAN network as shown next.
