Chapter 1: Introduction
Cable/DSL Router
The Network Everywhere Cable/DSL 4-Port Router connects multiple PCs to
your cable or DSL modem. And using the Setup Wizard, you can set up your
network quickly—just enter your Internet connection settings and let the
Wizard do the work!
The Router lets your PCs share one IP address from your ISP, files, printers,
and other resources. Use the Router as a DHCP server so it automatically
assigns internal IP addresses to your PCs. For network security, the Router’s
built-in Network Address Translation (NAT) feature helps protect your internal
network. Universal Plug and Play makes your networking experience as easy as
possible.

Simply put, a
router
is a network device that connects two networks together.
In this instance, the Router connects your
Local Area Network (LAN)
, or the
group of PCs in your home or office, to the
Wide Area Network (WAN)
,
which is the Internet. The Router processes and regulates the data that travels
between these two networks.
Think of the Router as a network device with two sides:
the first side interacts
with your private
Local Area Network (LAN)
of PCs.
The other, public side
interacts with the Internet, or the
Wide Area Network (WAN)
, outside of your
home or office.
The Router’s firewall protects your network of PCs so users on the public,
Internet side cannot “see” your PCs.
This is how your network remains private.
The Router protects your network by inspecting every data packet coming in
through the Internet (or WAN) port before delivery to the final destination on
the LAN port. The Router inspects Internet port services like the web server,
ftp server, or other Internet applications, and, if allowed, it will forward the
packet to the appropriate PC on the LAN side.
Remember that the Router’s ports connect to two sides. Your 10/100
LAN
port(s) connect to the LAN, and the Internet (or WAN) port connects to the
WAN.
The LAN port(s) transmit data at 10 or 100 Mbps, whereas the broad-
band or WAN port, or Internet port, transmits data at 10 or 100 Mbps.
What’s an IP Address?
IP
stands for Internet Protocol. Every device on an IP-based network, including
PCs, print servers, and routers, requires an
IP address
to identify its “location,”
or address, on the network.
This applies to both the WAN and LAN connections.
There are two ways of assigning an IP address to your network devices. You can
assign static IP addresses or use the Router to assign IP addresses dynamically.
Static IP Addresses
A
static IP address
is a fixed IP address that you assign manually to a PC or
other device on the network.
Since a static IP address remains valid until you
disable it,
static IP addressing
ensures that the device assigned it will always
have that same IP address until you change it.
Static IP addresses are com-
monly used with network devices such as server PCs or print servers.
