This solution applies to all Barracuda SSL VPNs, all firmware versions.
Log in to the appliance console on http, port 8000, and navigate to Advanced > Firmware. You will be able to see the latest version of the firmware that is available under the Firmware Download header. You can use this page to update, apply firmware releases, or to revert your firmware to a previous version. If a firmware update causes unexpected issues, we strongly recommend contacting Barracuda Networks Technical Support before reverting to a previous version.
Caution: Firmware updates require rebooting the Barracuda SSL VPN that temporarily interrupts your firewall service. To minimize interruptions, Barracuda Networks recommends updating the firmware after peak business hours.
There are two categories of new firmware that are described below:
- System Firmware Version: Displays the current version of firmware being used by the Barracuda SSL VPN. If release notes accompany a version, a link to the notes displays.
- Latest Version Available: Displays the latest version of firmware available from Barracuda Central for use by the Barracuda SSL VPN. Click Download Now to download the latest available version. After the download is complete, click Apply Now to install and activate the firmware on your system.
Warning: Firmware updates may require several minutes to install. To avoid damaging your hardware, do not power OFF the unit until the update is complete. The unit resumes protecting your network from viruses after the firmware update process is complete.
