Introduction
The D-Link DI-707P Broadband Router includes 7 ports and a printer port. It
provides a complete solution for Internet surfing and office resources sharing.
It is an ideal way to extend the reach and number of computers connected to
your network.
After completing the steps outlined in the Quick Installation Guide (included in
your package) you will have the ability to share information and resources, as
well as share a printer on your network.
The DI-707P is compatible with most popular operating systems, including
Macintosh, Linux and Windows, and can be integrated into a large network.

VPN Pass-Through supported
Supports pass-through PPTP sessions and allows you to setup VPN server
and VPN clients
Printer sharing (Optional)
Embeds a print server to allow all of the networked computers to share one
printer
Firewall
All unwanted packets from outside intruders are blocked to protect your
network
DHCP server supported
All of the networked computers can retrieve TCP/IP settings automatically
from the DI-707P
Web-based configuration
Configurable through any networked computer’s web browser using
Netscape or Internet Explorer
Printer Port.Most printers will work with
this bi-directional printer port. If you
experience difficulties with a multi-
functional printer, please confirm that your
printer is compatible with a bi-directional
port.

Features & Benefits continued
Access Control supported
Allows you to assign different access rights for different users
Packet filter supported
Packet Filter allows you to control access to a network by analyzing the
incoming and outgoing packets and letting them pass or halting them
based on the IP address of the source and destination.
Virtual Server supported
Enables you to expose WWW, FTP and other services on your LAN to be
accessible to Internet users.
User-Definable Application Sensing Tunnel
User can define the attributes to support special applications requiring
multiple connections, like Internet gaming, video conferencing, Internet
telephony and so on. The DI-707P can sense the application type and
open a multi-port tunnel for it.
DMZ Host supported
Allows a networked computer to be fully exposed to the Internet; this
function is used when the special “application-sensing tunnel feature” is
insufficient to allow an application to function correctly
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 con-
nected 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. 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.

Introduction to Virtual Private Networking
Virtual Private Networking (VPN) uses a publicly wired network (the Internet) to se-
curely 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.
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.
