CHAPTER 12
LAN
12.1 Overview
This chapter describes how to configure LAN settings.
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.
Figure 70 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical network
into logical networks.
12.2 What You Can Do
•Use the IP screen to change the IP address for your NBG6716 (Section 12.4 on page 118).
•Use the IP Alias screen to have the NBG6716 apply IP alias to create LAN subnets (Section 12.5
on page 119).
12.3 What You Need To Know
The actual physical connection determines whether the NBG6716 ports are LAN or WAN ports.
There are two separate IP networks, one inside the LAN network and the other outside the WAN
network as shown next.
