Introduction 
The D-Link DFL-100 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 DFL-100.   
 
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 DFL-100 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 DFL-100 has 3 LAN ports and 
one DMZ port.  That means that 3 computers can share the benefits of the 
DFL-100- equipped network and 1 computer can be configured as a server 
for Internet applications that may conflict with the advanced protection from 
intrusion offered. 
 
For the price of one Internet account, the DHCP-capable DFL-100 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-100, 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.
