LAN
This chapter describes the screens that display when you click LAN in the toolbar.
3.1 LAN OVERVIEW
This section describes some of the concepts related to the LAN screens.
3.1.1 LOCAL AREA NETWORKS
A Local Area Network (LAN) is a network of computers and other devices that usually
occupies a small physical area (a single building, for example). Your CVE-30360’s
LAN consists of all the computers and other networking devices connected to the
LAN 1~4 ports. This is your private network (in routing mode - see Routing Mode on
page 28).
The LAN is a separate network from the Wide Area Network (WAN). In the case of
the CVE-30360, the WAN refers to all computers and other devices available on the
cable (CATV) connection.
By default, computers on the WAN cannot identify individual computers on the LAN;
they can see only the CVE-30360. The CVE-30360 handles routing to and from
individual computers on the LAN.
3.1.2 LAN IP ADDRESSES AND SUBNETS
IP addresses on the LAN are controlled either by the CVE-30360’s built-in DHCP
server (see DHCP on page 27), or by you (when you manually assign IP addresses
to your computers).
For more information about IP addresses and subnets in general, see IP Addresses
and Subnets on page 25.
