7.0.2 Release Notes

  • Last updated on

Barracuda Networks recommends to always install the latest firmware release of the major version to benefit from the latest security and stability improvements.

This firmware version includes a critical security issue resolved by installing Hotfix 834. If Hotfix 825 is already installed use Hotfix 839 instead. For more information, see Hotfix 834 - Security Issue and Hotfix 839 - Security Issue.

Before installing or upgrading to the new firmware version:

Do not manually reboot your system at any time while the update is in process, unless otherwise instructed by Barracuda Networks Technical Support. Upgrading can take up to 60 minutes. For assistance contact Barracuda Networks Technical Support.


To keep our customers informed, the Known Issues list and the release of hotfixes resolving these known issues are now updated regularly.

  • 16.03.2017 – Firmware version 7.0.2 released.
  • 24.03.2017 – Added information about the automatic license update daemon.
  • 19.10.2017 – Release Hotfix 848 KRACK Attack.
  • Back up your configuration.
  • The following upgrade path applies – 5.2 > 5.4 > 6.0 > 6.1 (optional) > 6.2 (optional) > 7.0.2
  • Before updating, read and complete the migration instructions.

For more information, see Migrating to 7.0.

As of January 31, 2019, the first-generation ATP cloud services used by default with firmware versions 6.2.x, 7.0.x, 7.1.0, 7.1.1, and 7.2.0 will be discontinued. Firewalls using ATP must switch to the second-generation ATP cloud service, which is known as Barracuda Advanced Threat Protection (BATP).

For more information, see 7.0 Migration Notes.

What´s New in Version 7.0.2

Migrating to a New Hardware Model Wizard

A new wizard now helps you to migrate PAR files created on hardware firewall models either to the next larger model or to a different revision of the same model. The PAR file migration wizard automatically changes default values to fit the new model unless the settings have been changed by the admin. The migration is available for both stand-alone and managed firewalls.

For more information, see Migrating to a New Hardware Model and How to Migrate Managed Hardware Firewalls to a New Model.

NextGen Firewall available in Google Cloud

The F-Series Firewall can be deployed to the Google Cloud Platform to secure and connect your cloud resources. The NextGen Firewall can be deployed either by uploading the disk image available from the Barracuda Networks download portal, or by using the marketplace image in Google Launcher.

For more information, see Google Cloud Deployment.

Integrated Barracuda DSL Modem

This release provides firmware support for upcoming NextGen Firewall F82 DSL model with integrated xDSL modem. Some NextGen Firewall models now feature a built-in DSL modem supporting ADSL and VDSL connections.

For more information, see xDSL WAN Connections and How to Configure an xDSL WAN Connection with an Internal DSL Modem in Bridge Mode.

Automatic License Updates on Stand-Alone Firewalls

New firewalls now continuously check and, if necessary, update their licenses with the newest version available from the Barracuda licensing servers. The Box Activation Daemon is disabled by default for managed firewalls and firewall updated to 7.0.2. If the box activation daemon is disabled, licenses must be downloaded and updated via NextGen Admin for standalone firewalls, or through the Control Center for managed firewalls.

For more information, see Migrating to 7.0.
