connect to the Internet.
The following diagram illustrates the common network environment for Internet connection from
the local area network.

LAN
As shown in the above example, the local area network is composed of segments. One is
directly connected to a router to which a global IP address is assigned, and others are for the cli-
ent computers.
To enable Internet access from the local area network, assign a global IP address, which is an
IP address used on the Internet, to a router, and share it with other machines. In the above
example, a private IP address is assigned to all the machines in the local area network, and a
global IP address can be shared in each machine by the router using NAT (Network Address
Translation). Therefore, client computers and servers can connect to the Internet via the router.
It is recommended to set up the equipment to a segment other than those for routers connecting
to the Internet for security's sake.
Correct setup of the DNS server and mail server is required for sending/receiving an InternetFax
or an Email using the Internet. When setting the DNS server and mail server to enable the func-
tions provided in this equipment, refer to the following information.
