Update Firmware

  • Last updated on

Read the entire article before upgrading your Barracuda SSL VPN.

The Barracuda SSL VPN firmware is available as:

  • General Release (GA) – The latest generally available firmware from Barracuda Central.
  • Early Release (EA) – The newest version of firmware available for early access from Barracuda Central.

General Release

GA firmware is the final and fully tested firmware version. Barracuda Networks highly recommends that you download the GA release as soon as it is available to take advantage of important new features and fixes.

Early Release

EA firmware is available for early adopters who wish to test the latest firmware from Barracuda Networks, or who have a specific need for early access, such as a new feature or bug fix that would be beneficial to your environment.

 The firmware "apply" process takes several minutes to complete, and will cause the Barracuda SSL VPN to automatically reboot. Do not manually power-cycle the Barracuda SSL VPN at any time during the upgrade process, as doing so can potentially cause firmware corruption.

  3. If a new firmware version is available, click Download Now next to the version (GA or EA) you want to upgrade to.
