Powering up the DFL-1000
Connect the power cord to the DFL-1000 and plug it in. The Power
indicator on the front panel will light up and then the Status light will begin
flashing, indicating that startup has begun. After about 45 to 60 seconds
the DFL-1000 will be ready for use.
Configuring the DFL-1000
There are two ways to configure the network interface addresses of the
DFL-1000.
1. Using Microsoft Internet Explorer © web interface:
• Set the IP address of your management computer to 192.168.1.2 with netmask
255.255.255.0
• Connect the management computer to the Internal interface of the DFL-1000
through an crossover ethernet cable or network hub
• In the Internet Explorer Address Bar enter https://192.168.1.99
• Enter "admin" for the user name, leave the password blank and click OK
• Click on System and then on Network. Addresses can be viewed and set on
the IP Address page.
• Once the addresses are set you are ready to connect the DFL-1000 to your
network. Section 6 below will guide you through this process.
2. Using command line interface:
• Connect one end of the null-modem serial cable to the Console connector at
the front of the DFL-1000 and connect the other end to the serial port of an
administration computer or terminal.
• Start a terminal program, for example the HyperTerminal included with the Win-

dows operating system.
• For the terminal port parameters set Bits per Second to 115200, Data bits to 8,
Parity to None and Stop bits to 1.
• At the Login prompt type admin, no password required.
• Follow the instructions in the next section to set the interface addresses.
Setting the IP Addresses
First set the internal interface address to be in your internal network.
For example:
• set interface internal address 192.168.100.165
Next set the mask for your internal subnet:
• set interface internal netmask 255.255.255.0
Now set up the external interface:
• set interface external address 172.16.0.85
• set interface external netmask 255.255.255.224
Set the default gateway to the gateway address provided by your ISP:
• set defaultgw 172.16.0.94
At this point you should check the current settings.
Use the following command:
• get system interface
If the DMZ address is in the same subnet with the Internal or External
interfaces it will have to be changed. Otherwise it does not need to be
set at this point. To change it use:
• set interface dmz address 10.10.10.114
• set interface dmz netmask 255.255.255.0

In the event of difficulties you can restore the factory default settings with
the following command:
• set system status reset
When you are finished with the console you can log out using the com-
mand:
• quit
Connecting to Your Network
Connect the Internal Interface to an Internal Network Hub or Switch using
a straight Ethernet cable.The Link indicator will light up if the connection is
to a 100 megabit device.
Connecting to the Internet
Connect the External Interface to the Internet by running an Ethernet

cable from the DFL-1000 External Interface to the Public Switch or Router
provided by your Internet Service Provider.
Advanced Configuration
Now that you have completed the basic network setup, the DFL-1000
should be operating with the default policy, which is to allow all traffic origi-
nating from Internal to reach outside, and deny all traffic originating from
the Internet. The default security level for Virus Protection is Low. You
can regularly go to visit tsd.dlink.com.tw web site for updating virus scan
database.
Now you are ready to begin the Advanced Configuration of the DFL-1000.
