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 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 CAT5 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. ANIC 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.
Introduction to Virtual Private Networking
Virtual Private Networking (VPN) uses a publicly wired network (the
Internet) to securely connect two different networks as if they were the same
network. For example, an employee can access the corporate network from home
using VPN, allowing the employee to access files and printers. Here are several
different implementations of VPN that can be used.

-8-
Point-to-Point Tunneling Protocol (PPTP)
PPTP uses proprietary means of connecting two private networks over the
Internet. PPTP is a way of securing the information that is communicated between
networks. PPTP secures information by encrypting the data inside of a packet.
IP Security (IPSec)
IPSec provides a more secure network-to-network connection across the Internet
or a Wide Area Network (WAN). IPSec encrypts all communication between the
client and server whereas PPTP only encrypts the data packets.
Both of these VPN implementations are used because there is not a standard for
VPN server software. Because of this, each ISP or business can implement its
own VPN network making interoperability a challenge.

Installation Requirements
The DI-704P can be positioned at any convenient place in your office or house.
No special wiring or cooling requirements are needed. However, you should
comply with the following guidelines:
lPlace the DI-704P on a flat horizontal plane.
lKeep away from any heating devices.
lDo not place in a dusty or wet environment.
The recommended operational specifications of the DI-704P are:
Temperature 32o F ~ 131o F
Humidity 5 % ~ 90 %
In addition, remember to turn off the power, remove the power cord from
the outlet, and keep your hands dry when you install the hardware.

-12-
Network Settings
To use the DI-704P correctly, you have to properly configure the network settings
of your computers.
The default IP address of the DI-704P 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 Appendix Bto configure it. For
example,
1. configure IP as 192.168.0.3, subnet mask as 255.255.255.0 and gateway
as 192.168.0.1, or more conveniently,
2. configure your computers to load TCP/IP setting automatically, that is,
via the DHCP server of the DI-704P.
After installing the TCP/IP communication protocol, you can use the ping
command to check if your computer has successfully connected to the DI-704P.
The following example shows the ping procedure for Windows 95 platforms. First,
execute the ping command
ping 192.168.0.1
If the following messages appear:
Pinging 192.168.0.1 with 32 bytes of data:
Reply from 192.168.0.1: bytes=32 time=2ms TTL=64
a communication link between your computer and the DI-704P has been
successfully established. However, if you get the following messages:
Pinging 192.168.0.1 with 32 bytes of data:
Request timed out.
this indicates that the installation is not successful. Please check the following
items in sequence:
1. Is the Ethernet cable correctly connected between the DI-704P
and your computer?
The LAN LED of the DI-704P and the link LED of the network adapter card
on your computer must be lighted.

-13-
2. Is the TCP/IP of your computers properly configured?
If the IP address of the DI-704P 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 where “X” represents a number between 2 and 254.) The default
gateway must be 192.168.0.1.

-14-
Configuring the Ethernet Broadband Router
The DI-704P provides Web based configuration. You can configure your DI-704P
through your Netscape Communicator or Internet Explorer browser in MS
Windows, Macintosh or UNIX based platforms.
Start-up and Log in
Activate your browser, and disable the proxy or add the IP address of the
DI-704P into the exceptions . Then, type the IP address of the DI-704P into the
Location (for Netscape) or Address (for IE) field and press “Enter.”For example:
http://192.168.0.1.
After the connection is established, you will see the web user interface. There
are two appearances of web user interface: for general users and for the system
administrator.
To log in as an administrator, enter the system password (the factory setting

-15-
is ”admin”) in the System Password field and click on the Log in button. If the
password is correct, the web appearance will be changed into administrator
configure mode. As listed in its main menu, there are several options for system
administration.
