3.1.1

WAN AND LAN

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 CGN2'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
The LAN is a separate network from the Wide Area Network (WAN). In the case of
the CGN2, the WAN refers to all computers and other devices available on the cable
connection.
By default, computers on the WAN cannot identify individual computers on the LAN;
they can see only the CGN2. The CGN2 handles routing to and from individual
computers on the LAN.
