Introduction to Broadband

Router Technology

A router is a device that forwards data packets from a source to a destination.

Routers can work on Open System Interconnection (OSI) layer 3, which for-

wards data packets using an IP address 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 request sent and the information received by your com-

puter 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 elimi-

nating information that should not be there. This provides security for the com-

puters behind your router because computers from the outside cannot access

or send information directly to any computer on your network. The router deter-

mines 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 pre-

vents unauthorized access to or from your network. A firewall can be a com-

puter 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 unautho-

rized Internet users from accessing private networks such as corporate LANs

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 applica-

tion 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

A Local Area Network (LAN) is typically an Ethernet-based network that con-

nects several computers together over a small area such as a building or group

of buildings. LAN’s can also be connected over large areas. A collection of LANs

connected over a large area is called a Wide Area Network (WAN).

There are many types of media that can connect computers together. The most

common media is CAT5 cable; UTP or STP twisted pair wire. Each computer

must have a Network Interface Card (NIC), which transfers the data between

computers. A NIC is usually a 10/100Mbps Fast Ethernet adapter.

Most networks use hardware devices such as hubs or switches to transfer

data between computers. A hub receives 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 port (or corresponding computer) that each packet of

data is supposed to be delivered to. A switch minimizes network traffic and

speeds up communication over a network.

There are many types of scenarios to consider which could affect the operabil-

ity of a network. Some of these issues are discussed in the manual under the

Networking Basics

section.

Sample Scenario

You will need

broadband Internet access (a Cable or DSL subscription line into

your home or office).

Consult with your Cable or DSL provider for proper installation of the modem.

Connect the Cable or DSL modem to the DI-704UP wireless broadband router.

(

See the Quick Installation Guide included with the DI-704UP.

)

If you are connecting a desktop computer that does not already have an avail-

able Ethernet port to your network, you can install the D-Link

DFE-530TX+

Ethernet adapter into an available PCI slot. (See the Quick Installation Guide

included with the DWL-530TX+.)

If you are connecting a laptop computer without an available Ethernet port to

your network, install an Ethernet Cardbus adapter (

e.g

., D-Link DFE-690TXD)

and its drivers into the laptop computer. (See the Quick Installation Guide

included with the DFE-690TXD.)

** Easily upgrade to a wireless network by adding a wireless Access Point (D-Link DWL-900AP+) **

Connect your USB printer to the USB printer port on the DI-704UP. Please

refer to the Quick Installation Guide for loading the Windows print server

software if on a Windows-based computer.
