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 allow your PC’s IP settings be automatically assigned by
a DHCP server. By default, your new DFL-600 VPN Firewall functions as a DHCP
server, and it will give your PC the necessary IP settings, every time you boot your
PC.

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. To connect to the DFL-600’s web-based
management utility, type the IP address https://192.168.0.1 into the Address
field of your web browser. The https specifies the secure version of http.
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
