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.

it OS independent.

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
