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.
