Description:

In some cases it can be necessary to revert back to the old firmware after a firmware update (e.g. when a feature doesn't work as intended). During the upgrade process of a LANCOM R&S®Unified Firewall to a firmware version 10.5 and higher a recovery point is created automatically, so that a downgrade to the old version is possible.

This article describes the procedure for a firmware downgrade using a recovery point on a LANCOM R&S®Unified Firewall.

Recovery points are created only when updating to a major release firmware (e.g. from 10.4 to 10.5) but not within a release version (e.g. 10.5 Rel to 10.5 RU2).


Requirements:

  • LANCOM R&S® Unified Firewall with LCOS FX as of version 10.5
  • Web browser for configuring the Unified Firewall.

    The following browsers are supported:
    • Google Chrome
    • Chromium
    • Mozilla Firefox


Procedure:

1) Open the configuration of the Unified Firewall in a web browser and click on the option System → Recovery Points in the upper right corner.

2) Click Recover for the desired Recovery Point to revert back to this firmware.
