7.1 Overview
A Local Area Network (LAN) is a shared communication system to which many networking devices are
connected. It is usually located in one immediate area such as a building or floor of a building.
Use the LAN screens to help you configure a LAN DHCP server and manage IP addresses.

• Use the Static DHCP screen to assign IP addresses on the LAN to specific individual computers based
on their MAC Addresses ( Section 7.3 on page 55 ).
• Use the UPnP screen to enable UPnP and UPnP NAT traversal on the PMG2006-T20A ( Section 7.4 on

7.1.2.1 About LAN
IP Address
IP addresses identify individual devices on a network. Every networking device (including computers,
servers, routers, printers, etc.) needs an IP address to communicate across the network. These
networking devices are also known as hosts.
Subnet Mask
Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet
masks to divide one network into multiple sub-networks.
