Restoring system settings to factory defaults

Use the following procedure to restore system settings to the factory defaults. This

procedure will possibly change the DFL-200 firmware version to a lower version if it has been

upgraded.

Make sure you have the current firmware file available for upload to the device in

the case where the firmware version is defaulted to an older version.

The factory reset procedure erases all configuration changes that have been made to the

DFL-200 and will revert the system to its original configuration, including resetting interface

addresses.

Follow these steps to reset the DFL-200 to factory default settings through the Web-based

Configuration:

Step 1

. Under the

Tools

menu and the

Reset

section, click on the

Reset to Factory

Defaults

button.

Step 2

. Click

in the dialog to reset the unit to factory defaults, or press

Cancel

cancel.

Follow these steps to reset the DFL-200 to factory default settings using the Reset button

located at the rear of the device:

Step 1.

Using a paperclip or some other rigid small diameter object push in and hold the

Reset button for 15 seconds while the DFL-200 is powered on.

Step 2.

The Power light will go out to indicate the device is restarting with the factory

default configuration.

Step 3.

Allow 2 minutes for the Firewall to completely restart. At this point the firewall can

be accessed via its default LAN IP (192.168.1.1) through a web browser. The first login

will require the use of the Wizard to complete basic connectivity configurations.

You can restore your system settings by uploading a previously generated system

configuration file to the DFL-200 if a backup of the device has been downloaded to your Local

Machine Prior to reset.
