CHAPTER 13
LAN
13.1 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 74 LAN Example
The LAN screens can help you configure a manage IP address, and partition your physical
network into logical networks.
13.2 What You Can Do
•Use the IP screen to change the IP address for your NBG5615 (Section 13.4 on page 130).
•Use the IP Alias screen to have the NBG5615 apply IP alias to create LAN subnets (Section 13.5
on page 131).
13.3 What You Need To Know
The actual physical connection determines whether the NBG5615 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.
