6. Using the Firewall Setup Wizard
To run the Setup Wizard, you must connect to the DFL-500 web- based manager. You require:
• A management computer with an ethernet connection
• Internet Explorer version 4.0 or higher
• A crossover cable or an ethernet hub and two ethernet cables
To run the Setup Wizard:

1. Set the IP address of the computer with an ethernet connection to the static IP address
192.168.1.2 and a netmask of 255.255.255.0.
2. Using the crossover cable or the ethernet hub and cables, connect the internal interface of the
DFL-500 to the computer ethernet connection.
3. Start Internet Explorer version 4.0 or higher. Type https://192.168.1.99 into the Address field
and press Enter.
Your browser connects to the web- based manager and the DFL-500 login page appears.
4. Type admin in the Name field and select Login.
5. Select the Wizard button at the upper right of the web- based manager to start the setup
wizard.
6. Use the information you gathered on the first two pages of this Quick Install Guide to fill in the
wizard fields as required. Select next to step through the wizard pages.
7. Confirm your configuration settings and then select Finish and Close.
You are ready to connect the DFL-500 to your network.
7. Basic configuration using the CLI
As an alternative to the setup wizard, you can use the command line interface (CLI) to configure the
DFL-500.
To use the CLI:
1. Connect one end of the null-modem cable to the DFL-500 Console (RS-232 serial) connector
and connect the other end to a serial port of a management computer or terminal.
2. On the management computer, start a terminal program such as HyperTerminal.

3. Set the Baud Rate (bps) to 9600, Data bits to 8, Parity to None, Stop bits to 1, and flow control
to None.
4. Press Enter to connect to the DFL-500.
5. At the
D-Link Login: prompt, type admin and press Enter twice.
6. Set the internal interface to the Internal IP Address and netmask.
For example, to set the internal interface to IP address 192.168.1.1 and netmask to
255.255.255.0 enter:
set system interface internal ip 192.168.1.1
255.255.255.0
7. Set the external interface to the External IP Address and Netmask.
For example, to set the Manual IP address to 204.23.1.5 and netmask to 255.255.255.0
enter:
set system interface external ip 204.23.1.5
255.255.255.0
To set the external interface to use PPPoE and to set the PPPoE user name to
username and the PPPoE password to password enter:
set system interface external pppoe enable username
password
To set the external interface to use DHCP enter:
set system interface external dhcp enable
8. To check your changes, enter:
get system interface
9. Set the default route to the Default Gateway IP address.
For example to set the default route to 204.23.1.2 enter:
set system route add 0.0.0.0 0.0.0.0 gw 204.23.1.2 dev
external
Once these addresses are set, you are ready to connect the DFL-500 to your network.

8. Connecting the DFL-500
There are two 10/100 BaseTX connectors on the DFL-500:
• Internal for connecting to your internal network
• External for connecting to your public switch or router and the Internet
To connect the DFL-500:
1. Connect the Internal interface to the hub or switch connected to your internal network.
2. Connect the External interface to the public switch or router provided by your Internet Service
Provider.
9. Advanced configuration
You have completed the basic network setup of your DFL-500. By default all traffic originating from
your Internal network is allowed to reach the Internet, and all traffic originating from the Internet is
blocked from reaching your internal network.

You can continue configuring the DFL-500 by connecting to the web-based manager from the internal
network. Browse to https:// followed by the IP address of the DFL-500 internal interface.
You can now customize your DFL-500 configuration using the information in the DFL-500 User
Manual and in the DFL-500 web- based manager online help.
You can:
• Customize the firewall configuration
• Add and configure IPSec, PPTP, and L2TP VPNs
• Configure the Network Intrusion Detection (NIDS)
• Customize virus and worm protection
• Configure logging and reporting
• Customize the DFL-500 system configuration
Transparent mode
This Quick Install Guide describes how to configure the DFL-500 to run in Network Address
Translation (NAT) mode. You can also configure the DFL-500 to run in Transparent mode. Refer to
the Transparent mode installation chapter of the DFL-500 User Manual.
10. Troubleshooting
Reconnecting to the web- based manager
If you changed the IP address of the internal interface, you must reconnect to the web- based
manager by browsing to https:// followed by the new IP address. You may also have to change the
IP address of the management computer to be on the same subnet as the internal interface.
Restarting the DFL-500
At any time during the installation process if the DFL-500 is not responding correctly, you can shut it
down and restart it.
Using the web-based manager:
• Go to System > Status.

• Select Restart.
Using the CLI:
• Enter the command.
execute reboot
You can cycle the power on the DFL-500 using the power switch on the back of the unit.
Resetting the DFL-500 to the factory default configuration
If restarting does not solve the problem, you can restore the DFL-500 to its factory default
configuration.
Using the web-based manager:
• Go to System > Status.
• Select Restore Factory Defaults and select OK.
The DFL-500 restarts with the configuration that it had when first powered on.
Using the CLI:
• Enter the command.
execute reset
The DFL-500 restarts with the configuration that it had when first powered on.
