2.4.1. Reset to Factory Defaults

It is possible to apply the original defaults that existed when the D-Link Firewall was purchased.
These defaults can be applied only to the current configuration or to the entire hardware unit. The
latter option essentially restores the unit to the state it was in when it left the factory.
Example 2.12. Reset to Factory Defaults with the standard user interface
Web Interface
1. Go to Maintenance > Reset
2. Select Reset the configuration to Factory Defaults then confirm and wait for the restore to complete, OR
3. Select Reset the entire unit to Factory Defaults then confirm and wait for the restore to complete.
Reset alternative via the Serial Console
Connect the serial cable and connect with a console using a terminal emulator software product. If
Microsoft Windows is being used, "HyperTerminal" can be used. Reset the firewall. Press a key
when the "Press any key to abort and load boot menu" message appears at the console. When the
boot menu appears, select the desired option then confirm and wait for the process to complete.
Reset alternative for the DFL-210/260/800/860 only
To reset the DFL-210/260/800/860 you must hold down the reset button at the rear panel for 10-15
seconds while powering on the unit. After that, release the reset button and the DFL-210/800 will
continue to load and startup in default mode, i.e. with 192.168.1.1 on the LAN interface.
Reset alternatives for the DFL-1600 and DFL-2500 only
Press any key on the keypad when the "Press keypad to Enter Setup" message appears on the dis-
play. Select "Reset firewall", confirm by selecting "Yes" and wait for the process to complete.

2.4.2. Configuration Backup and Restore

The configuration of D-Link Firewalls can be backed up or restored on demand. This could, for in-
stance, be used to recall the "last known good" configuration when experimenting with different
configuration setups.
Example 2.13. Configuration Backup and Restore
Web Interface
To create a backup of the currently running configuration:
Warning
DO NOT ABORT THE RESET TO FACTORY DEFAULTS PROCESS. If aborted the
firewall can cease to function properly.
