Managing D-Link DFL-200

When a change is

done to the configuration a new icon named Activate Changes will appear. When all changes and administrator would like to do is done the changes need to be saved and activated to take effect, this is done by clicking on the

Activate Changes button on the Activate Configuration Changes page. What will happen is that the firewall will save the configuration and reload it, letting the new changes take effect. But for the changes to

become permanent the admin need to login again. This have to be done before a configurable timeout has been reached, this can be set on the Activate Configuration Changes page, by choosing the time from the dropdown menu.

Resetting the DFL-200

To reset the DFL-200 to factory default settings you must hold the reset button down for at least 15 seconds after powering on the unit. You will first hear one beep, which will indicate that the firmware have started and the restoring have started, keep the button pressed in until you hear two consecutive beeps shortly after each other. After this you can release the reset button and the DFL-200 will continue to load and startup in default mode, i.e. with 192.168.1.1 on the LAN interface.
