7.2.1 EA2 Release Notes

  • Last updated on
Early Release

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

The 7.2.1 EA2 release will not be displayed in the dashboard element of CloudGen Admin and will not be listed in the Control Center as a firmware update.

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.

  • 2018-05-28 – Firmware version 7.2.1 EA2 released.
  • 2018-11-21 – Hotfix 889 - Virus Scanner (CloudGen Firewall) – By installing this hotfix, the Avira scanning engine will be updated to version 4 and update virus definitions even after September 30th 2019. For more information, see Hotfix 889.
Before You Begin
  • Back up your configuration.
  • The following upgrade path applies – 5.2 > 5.4 > 6.0 > 6.1 (optional) > 6.2 (optional) > 7.0 (optional) > 7.1 (optional) > 7.2
  • Before updating, read and complete the migration instructions.

For more information and a list of supported CloudGen Firewall models, see 7.2.1 EA2 Migration Notes.

First-Generation ATP to Second-Generation Barracuda ATP Cloud Migration

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 7.2.1 EA2 Migration Notes.

What´s New in Version 7.2.1 EA2

CloudGen Firewall and Virtual Routing and Forwarding (VRF)

Virtual routing and forwarding (VRF) is a technology based on the operating principle of a physical router. Unlike a single router, virtual routers (VR) can be run simultaneously as multiple instances where each uses its own routing table. Virtual routing can be used to segment network paths without using additional devices. The concept of keeping traffic on multiple network paths separated offers a huge variety of applications.

For more information, see Virtual Routing and Forwarding (VRF).


CloudGen Firewall and RSTP

The CloudGen Firewall now supports Layer 2 bridging with RSTP. The configuration of RSTP is fully integrated into the configuration window of Layer 2 bridging.

For more information, see How to Activate RSTP.

Improved UI support for Configuration of Virtual IPs for Remote Management Tunnels

Splitting network addresses into subnets and preserving them for future use always leads to fragmentation, often at the cost of a good overview. Knowing which private address is already used and which addresses are still available is essential for the configuration of remote management tunnels. Configuring a remote management tunnel now is supported by a button that helps to find free private IP addresses quickly that are available for VIP addresses.

For more information, see How to Configure a Remote Management Tunnel for a CloudGen Firewall.


The Barracuda Reporting Server (BRS) is a hardware appliance purpose-built for rapidly generating reports while maintaining or improving the accuracy of reporting data. It also provides an aggregate view of data for customers with multiple connected devices.

For more information, see Barracuda Reporting Server (BRS) Integration.
