Introduction
The D-Link DFL-600 Broadband VPN Router enables your network to
connect to the Internet via a secure, private connection using a Cable or DSL
modem. The Virtual Private Network (VPN) that is created on the Internet
between your home and a VPN server in your office is secure from
interference when you use the DFL-600.
It is an ideal way to connect your computer to a Local Area Network (LAN).
After completing the steps outlined in the Quick Install Guide (included in
your package) you will have the ability to share information and resources,
such as files and printers, and take full advantage of a secure “connected”
environment.
Connect the WAN port on the DFL-600 to the Cable/DSL modem using an
Ethernet cable. Your entire LAN can now access the Internet using just one
Internet account. The DFL-600 has 3 LAN ports, one DMZ port, and one
WAN port. That means that 3 computers can share the benefits of the DFL-
600-equipped network and 1 computer can be configured as a server for
Internet applications that may conflict with the advanced protection from
intrusion offered by your new DFL-600.
For the price of one Internet account, the DHCP-capable DFL-600 will
automatically provide unique IP Addresses for all the computers on the
network. (DHCP stands for Dynamic Host Configuration Protocol. It is a
protocol for assigning IP Addresses automatically. With a DHCP router like
the DFL-600, there is no need to assign static IP Addresses, or purchase
multiple addresses from the ISP - Internet Service Provider.)
Everyone in your home can access the Internet on his or her own computer, at
the same time, without any noticeable decrease in speed.
With the serial port, you can connect an analog modem (dial-up modem) as a
back up in case of any difficulties that may arise with the Cable or DSL
connection.

With Firewall Protection, Hacker-attack logging, and Virtual Private
Networking, the DFL-600 provides a level of security suitable for many
businesses.
This manual provides a quick introduction to network technology. Please
take a moment to read through this manual and get acquainted with your
DFL-600.

IP Address Settings and Computer Settings
In order to install the DFL-600 you will need to check your computer’s
settings and the values from your ISP.
The information offered by your ISP:
• Dynamic IP settings
• Your fixed IP address for the gateway
• Your subnet mask for the gateway
• Your default gateway IP address
• Your DNS IP address
If you would like to use PPPoE, you will need the following values from your
ISP in order to install your router:
• User Name
• Password
The static IP settings for the PC:
• Your PC’s fixed IP address
• Your PC’s subnet mask
• Your PC’s default gateway
• Your PC’s primary DNS IP address
Note: The router’s default IP address setting is 192.168.0.1.
Dynamic IP Settings:
It is recommended that you leave your IP settings as automatically assigned (by a
DHCP server). By default, the gateway is a DHCP server, and it will give your
computer the necessary IP settings.

Introduction and Overview
The DFL-600 Firewall/VPN Router creates two separate networks on the
LAN side of your network −by default, a 192.168.0.0 subnet and a
192.168.1.0 subnet (both with a subnet mask of 255.255.255.0). The DFL-
600 routes packets between these two subnets and the Internet (or the
network connected to the DFL-600’s WAN port). The network address
information of the WAN network is usually provided by an Internet Service
Provider (ISP) or a network administrator.
The 192.168.0.0 network
− LAN. The three Ethernet ports labeled −Local
Area Network on the front panel, and 1, 2, and 3 on the rear panel −are, by
default, assigned the IP address range between 192.168.0.2 to 192.168.0.254.
So computers and other devices connected to these three ports either allow
the DFL-600’s DHCP server to assign them IP addresses from this range, or
you can manually assign devices connected to these ports an IP address from
this range. Remember that the IP address, 192.168.0.0, is reserved. The
DFL-600 is assigned 192.168.0.1 −on the LAN side −and is configured
from a computer (again, on the LAN side of your network) using a web
browser, at this IP address. In addition, you must specify the port number
8081. So, you must enter http://192.168.0.1:8081 in the address field of your
web-browser to access the DFL-600’s web-based configuration manager.
The 192.168.1.0 network
− DMZ. The port labeled −DMZ on both the front
and rear panel −is, by default, assigned the IP address range between
192.168.1.2 to 192.168.1.254 −with a subnet mask of 255.255.255.0. So
computers and other devices connected to this port must be assigned IP
addresses from this range. The DHCP server on the DFL-600 only services
the LAN ports, so you must manually assign a computer connected to the
DMZ port an IP address from this range.
You can use this default IP addressing scheme, or you can configure your
own. It is important to note that the three LAN ports and the DMZ port must
be on different subnets (different ranges of IP addresses) and that the
computers that are connected to these ports must have IP addresses in the
appropriate range.

The DMZ port is used to allow computers and devices connected to this port
to have more direct access to the Internet. This is useful for certain
applications that may conflict with the firewall and Network Address
Translation (NAT) features of the DFL-600. Computers and devices
connected to the DMZ port will not have the level of protection that the LAN
ports can provide, however. It is recommended that computers and devices
connected to the DFL-600’s DMZ port have some type of firewall software
installed and running to provide these devices with at least some level of
protection from unwanted intrusions from the Internet.
The Wide Area Network (WAN) side of the DFL-600 is anything connected
to the WAN port. This is normally an Ethernet connection to a Cable or DSL
modem that, in turn, provides a connection to the Internet. There are three
different methods for your ISP to provide the necessary network address
information to your DFL-600.
It can be useful when configuring your DFL-600 Firewall/VPN Router to
think of the LAN side (all computers or devices connected to the three LAN
ports or the DMZ port) and the WAN side (all computers or devices
connected to the WAN port). The WAN side of the router is connected to
some device that ultimately allows a connection to the Internet, while the
LAN side is connected to your computers or other network devices (such as a
switch or hub) that ultimately allows users access to the both the Internet and
any other devices on your LAN (such as a printer or scanner).
The network information (including the IP address) required by the WAN
side of the DFL-600 is either obtained automatically from your ISP (or other
network device on the WAN side) or is entered manually. The DFL-600
allows three methods for this information to be obtained, as follows:
Dynamic −your ISP uses the Dynamic Host Configuration Protocol (DHCP)
to provide the network information. Some ISP’s may require you to enter an
assigned Host Name, as well.
Static IP Address −your ISP assigns you an IP address that never changes.
This is more common in businesses that lease dedicated connections. If your
ISP uses this type of connection, you must manually enter the assigned IP

11
address, subnet mask, default gateway address, and primary and secondary
DNS addresses. This information will be provided by your ISP.
Point-to-Point Protocol over Ethernet (PPPoE) −this protocol requires the
use of a Username and Password to gain access to the network. In addition,
you can specify a Connect on Demand connection that will connect to the
Internet only when a computer or device on your LAN makes a request, or
when the DFL-600 is rebooted.
If you do not know the appropriate method of obtaining the WAN side
network address information, contact your ISP or network administrator.
The Device IP Settings dialog box allows you to specify the IP address that
computers on your LAN will use to access the DFL-600’s web-based
configuration utility. The default is 192.168.0.1 with a subnet mask of
255.255.255.0. If it becomes necessary to change this IP address, be sure to
use an address that is in the same range (on the same subnet) as the three
LAN ports, or you will not be able to access the DFL-600 from your LAN.
The many other features of the DFL-600 are described in subsequent sections.

Using the Configuration Utility
Launch your web browser and type the device IP address and port number
(http:// 192.168.0.1:8081) in the browser’s address box. This is the default IP
address of your DFL-600. Press Enter.
The following dialog-box will appear to prompt you to enter the DFL-600’s
default User Name and Password. The DFL-600’s default User Name is
admin and the default Password is also admin −all lower case.
Click OK to open the Home menu.
Note: Please make sure that the computer you will use to connect to and
configure the DFL-600 is assigned an IP address that is in the same range as
the DFL-600. The IP address of the DFL-600 is 192.168.0.1. All computers
on your network must be within that range, for instance, the computer IP
address could be any IP address from the range 192.168.0.2 to 192.168.0.254,
with a subnet mask of 255.255.255.0.

The Setup Wizard will guide you the most basic setup tasks, such as setting
an administrative password, selecting the type of WAN connection you have,
entering your computer’s host name (if required by your ISP), saving the
configuration and restarting the router.
All other setup tasks can be accomplished using the configuration utility from
your web browser.
To use the Setup Wizard, click on the Run Setup Wizard link. This will
start the Setup Wizard.

Setup Wizard
The Setup Wizard will guide you through the most basic setup tasks for the
DFL-600. All other configuration tasks can be accomplished through the
web-based manager.
The Home menu contains a Run Setup Wizard link. Click on this button to
run the Setup Wizard.
Click Next to continue.

Enter a password in the Password field, and again in the Verify Password
field. This will become the logon password for the DFL-600. This password
is case-sensitive, so remember to use capital letters when logging on to the
DFL-600’s web-based manager −if you enter a password with capital letters
here. The user name, admin, will not be changed here.
Note: If you choose to input a password, please remember it. If you lose your
password, you will have to manually reset the unit (using the reset button on
the rear panel of the unit). Resetting the DFL-600 will return all
configuration parameters to their factory default values, so all of your
settings will be lost and will need to be entered again. The default Username
is admin with a password that is also admin.
Click Next to continue.
15

This menu allows you to select the type of connection your ISP provides.
Many ISPs use the PPPoE (Point-to-Point Protocol over Ethernet) for DSL
connections, while many Cable ISPs use DHCP (Dynamic Host
Configuration Protocol). DHCP assigns an IP address for your Internet
connection each time you log on (and is therefore, a dynamic IP address).
DHCP is referred to as Dynamic IP address on the DFL-600. The Setup
Wizard will open a page with the appropriate fields for the entry of your ISP
contact information, depending upon which of the three options you choose.
The Static IP address click-box is used to enter a permanent IP address that
is assigned by your ISP. If your ISP assigns you a permanent IP address,
choose this option.
Click Next to continue.
16

Some ISPs require you to use an assigned host name for your Internet
connection. If your ISP requires this, you can enter the assigned host name in
the Host Name field.
If you selected Static IP Address on the Select Internet Connection Type
(WAN) wizard screen above, the following screen will open:
This screen will allow you to enter the static IP address information, if your
ISP has assigned a static IP address to your Internet account. Your ISP must
provide this information.
If you selected PPPoE (Point-to-Point Protocol over Ethernet) on the Select
Internet Connection Type (WAN) screen above, the following window will
open:
17

This screen will allow you to enter the PPPoE information, if your ISP uses
the PPPoE protocol for your Internet account. Your ISP must provide this
information.
Click Next to continue.
18

You have completed the basic setup Wizard. The configuration now needs to
be entered into the DFL-600’s flash RAM. Clicking Restart will save the
configuration and restart the router.
