Introduction
The D-Link DI-804V Broadband VPN Router enables your network to
connect to the Internet via a secure, private connection using a Cable/DSL
modem, such as the D-Link DCM-200 Cable Modem. The Virtual Private
Network that is created on the Internet between your home and your office
(with a VPN server) is secure from interference when you use the DI-804V.
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 “connected”
environment for work or play!
Connect the WAN port on the DI-804V to the Cable/DSL modem (e.g., the
DCM-200) using an Ethernet cable. Your entire LAN can now access the
Internet using just one Internet account. The DI-804V has 4 LAN ports.
That means that 4 computers can share the benefits of the DI-804V- equipped
network.
For the price of one Internet account, the DHCP-capable DI-804V 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 DI-804V, 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 DI-804V provides a level of security suitable for many
businesses.

IP Address Settings and Computer Settings
In order to install the DI-804V 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:
The dynamic IP settings for the PC. It is recommended that you leave your IP
settings as automatically assigned. By default, the gateway is a DHCP server, and it
will give your computer the necessary IP settings.

9
Using the Configuration Utility
Launch your web browser and type the device IP address (http:// 192.168.0.1)
in the browser’s address box. This IP address is the default value of your
gateway. Press Enter.
Note: Please make sure that the computer’s IP Address is in the same IP
Address range as the DI-804V. The IP Address of the DI-804V is
192.168.0.1. All computers on your network must be within that range, for
instance, the computer IP Address could be 192.168.0.x. All computers on
the network must have the same subnet mask.
The main menu appears showing all the settings available.

10
Basic Setup
Basic setup is a step-by-step process that will let you input all the basic
settings.
Click BASIC SETUP
A username and password screen will appear. Leave the password box empty
and type admin (the default username) in the username box.
Click OK
The Setup Wizard’s page will appear.
Note: If you choose to input a password at any time, please remember it. If
you should lose the password, you will need to reset the unit. After you reset
the DI-804V, all your settings will be lost and will need to be re-input.

11
Time Settings
Please choose your local time zone.
Device IP Settings
You have to give your VPN Gateway an IP address on your network. This is
not the IP address from your ISP but the local internal LAN IP address. The
IP address “192.168.0.1” is the default value of your gateway.
Device IP Address:
The internal LAN IP
address of your VPN
Gateway.
Device IP Subnet Mask:
The subnet mask can
usually be left as its
default entry
“255.255.255.0”.

12
Cable/DSL ISP Settings
To use the xDSL/Cable ISP settings, you must configure the router. ISP use
either static or dynamic IP addresses. Check with your ISP if you are not
certain which one it uses. If your ISP uses a static IP address, it means that
the IP address of your router is always the same. Most ISPs use dynamic IP
addresses. They assign you a new IP address every time you connect to the
Internet.
If you have a static IP address, do the following:
Enter the IP address that your ISP provided.
Enter the IP subnet mask.
Enter the ISP gateway address.
Enter the DNS IP address.

13
ISP Additional Settings (PPPoE Settings)
You can configure the router to use additional ISP settings. Some ISPs
require PPPoE for authentication purposes.
Do the following to set up PPPoE:
User name: Enter the user name of your ISP account.
Password: Enter the password of your ISP account.
Retype password: Enter the password of your ISP account again to re-
confirm.
Some ISPs use Host Name and Domain Name to authenticate the user; if this
is the case, you need to enter:
Host Name: Enter the name of the gateway.
Domain Name: Enter the domain name provided by your ISP
Some ISP require you input the LAN card Mac address; if this is the case,
you need to enter:
Mac Address: Enter this LAN card Mac address.
Note: Some ISPs may recognize your LAN card Mac address as a legal user;
in this case, you have to copy the LAN card Mac address in the Mac address
field.
For WIN 95/98 you can run winipcfg to see the LAN card Mac address.
For WIN/NT you can run ipconfig/all to see the LAN card Mac address.

14
Modem Settings
The modem dialup can be used as a backup for the xDSL/Cable connection.
If you would like to use the modem dialup or VPN features you must enable
