How do I reset a LANCOM R&S Unified Firewall to its factory default settings?


This document describes how you return a LANCOM R&S Unified Firewall to its factory default settings.

  • USB 2.0 stick with max. 32GB storage capacity. USB 3.0 sticks and very large sticks (>16GB) sometimes cause problems for the BIOS in Unified Firewalls.

To be able to download the USB installer and the ISO image file, you must be a LANCOM partner and have access to the LANcommunity portal.

As an end customer, you must contact one of our LANCOM partners so that they can provide you with the files.

1) Creating a bootable USB stick:

1.1) Download the file of the USB installer. The software does not have to be installed.

1.2) Download the ISO image file of the firewall operating system.

1.3) Insert a USB stick into your PC.

1.4) Start the USB installer software (rsuf_stick_10_2.exe) with administrator rights.

1.5) Select the desired language.

1.6) Click Next to start the wizard.

1.7) Accept the license agreement and click Next.

1.8) Select the path to the downloaded ISO image file.

1.9) Select the USB mass storage device where the image is to be installed.

1.10) Any data on the USB storage device will be irretrievably deleted during this process!

Confirm the process by activating the option.

1.11) Select Automatic installation with backup and Use default backup and click Next.

1.12) Select the recommended option Format as a USB hard drive.

1.13) Click Next to start the process.

1.14) The process log is shown in the dialog.

1.15) Once the process is completed successfully, the wizard reports “Configuration successfully completed”.

1.16) Leave the option Remove USB stick safely enabled and click Close.

1.17) Remove the USB stick from your PC.
    Please note:
    Make sure that the bootable USB stick is never connected to a computer which is booting up. Otherwise, the USB stick triggers an automatic installation of the LANCOM R&S Unified Firewall software and reformats the hard disks.

2) Resetting the Unified Firewall to factory settings:

Please note that the license for your Unified Firewall will be deleted after returning the device to its factory settings. The device is then returned to its 30-day trial period!

In order to re-license the device after resetting it, you must import the license file that you received when you first registered your device.

2.1) Turn the Unified Firewall off.

2.2) Plug the bootable USB stick created in step 1 into any USB port of the device.

2.3) Turn the Unified Firewall on to start the automatic installation of the new image.
    • Once the installation process has successfully completed, the device shuts off automatically.

2.4) Once the R&S Unified Firewall has switched itself off, you can remove the USB stick.

Please note:
We recommend that you format the USB stick after successfully installing the current version of the Unified Firewall software. This prevents you from unintentionally installing the image on other devices. This would cause hard drives to be formatted and data lost.

2.5) Continue with Chapter 2, “Getting Started” of the Unified Firewalls User Manual.
