Introduction (continued)
Technology Introduction
Introduction to Broadband Router Technology
A router is a device that forwards data packets from a source to a destination.
Routers forward data packets using IP addresses and not a MAC address. A
router will forward data from the Internet to a particular computer on your LAN.
The information that makes up the Internet gets moved around using routers.
When you click on a link on a web page, you send a request to a server to show
you the next page. The information that is sent and received from your computer
is moved from your computer to the server using routers. A router also
determines the best route that your information should follow to ensure that the
information is delivered properly.
A router controls the amount of data that is sent through your network by
eliminating information that should not be there. This provides security for the
computers connected to your router, because computers from the outside
cannot access or send information directly to any computer on your network.
The router determines which computer the information should be forwarded to
and sends it. If the information is not intended for any computer on your network,
the data is discarded. This keeps any unwanted or harmful information from
accessing or damaging your network.
Introduction to Firewalls
A firewall is a device that sits between your computer and the Internet that
prevents unauthorized access to or from your network. A firewall can be a
computer using firewall software or a special piece of hardware built specifically
to act as a firewall. In most circumstances, a firewall is used to prevent
unauthorized Internet users from accessing private networks or corporate LAN’s
and Intranets.
A firewall watches all of the information moving to and from your network and
analyzes each piece of data. Each piece of data is checked against a set of
criteria that the administrator configures. If any data does not meet the criteria,
that data is blocked and discarded. If the data meets the criteria, the data is
passed through. This method is called packet filtering.
A firewall can also run specific security functions based on the type of application
or type of port that is being used. For example, a firewall can be configured to
work with an FTP or Telnet server. Or a firewall can be configured to work with
specific UDP or TCP ports to allow certain applications or games to work
properly over the Internet.

Introduction (continued)
Introduction to Local Area Networking
Local Area Networking (LAN) is the term used when connecting several
computers together over a small area such as a building or group of buildings.
LAN’s can be connected over large areas. A collection of LAN’s connected over
a large area is called a Wide Area Network (WAN).
A LAN consists of multiple computers connected to each other. There are many
types of media that can connect computers together. The most common media
is Cat-5 cable (UTP or STP twisted pair wire.) On the other hand, wireless
networks do not use wires; instead they communicate over radio waves. Each
computer must have a Network Interface Card (NIC), which communicates the
data between computers. A NIC is usually a 10Mbps network card, or 10/
100Mbps network card, or a wireless network card.
Most networks use hardware devices such as hubs or switches that each cable
can be connected to in order to continue the connection between computers. A
hub simply takes any data arriving through each port and forwards the data to
all other ports. A switch is more sophisticated, in that a switch can determine
the destination port for a specific piece of data. A switch minimizes network
traffic overhead and speeds up the communication over a network.
Networks take some time in order to plan and implement correctly. There are
many ways to configure your network. You may want to take some time to
determine the best network set-up for your needs.

Getting Started (continued)
Network Settings
To use the DX-E401correctly, you have to properly configure the network settings
of your computers. The default IP address of the DX-E401 is 192.168.0.1, and
the default subnet mask is 255.255.255.0. These addresses can be changed
as needed, but the default values are used in this manual. If the TCP/IP
environment of your computer has not yet been configured, you can refer to
Configuring Your PCs to Connect to the DX-E401 to configure it.
For example:
Configure your computer IP as 192.168.0.3, subnet mask as
255.255.255.0 and gateway as 192.168.0.1.
Or more conveniently
Configure your computers to obtain TCP/IP settings automatically
from the DHCP server feature of the DX-E401.
Since the IP address of the DX-E401 is 192.168.0.1, the IP address of your
computer must be 192.168.0.X (where “X” is a number between 2 and 254.)
Each computer on your network must have a different IP address within that
range. The default gateway must be 192.168.0.1 (the IP address of the DXE401).
Configuring the DX-E401
The DX-E401 provides an embedded Web-based management utility making
it operating system independent. You can configure your DX-E401 through the
Netscape Communicator or Internet Explorer browser in MS Windows,
Macintosh, Linux or UNIX based platforms. All that is needed is a web browser
such as Internet Explorer or Netscape Navigator version 4 and higher with Java
Script enabled.
Start-up and Log in
Activate your web browser and type in the IP address of the DX-E401 into the
Location (for Netscape) or Address (for IE) field and press “Enter.” The default
