8.3.1 Release Notes

8.3.1 Release Notes

Important Announcements and Notes

Read this section before you continue with the Release Notes below.

Outdated technical features are subject to removal in order to keep the CloudGen Firewall up to date and performing properly. See the following two paragraphs for the features that will be removed in this release and the features that are subject to removal in upcoming releases.

Certain features will be removed completely because they have become technically obsolete; other features have become outdated and will be replaced by improved technology.

Features No Longer Supported as of the 8.3.0/8.3.1 Release

  • Generic Forwarder
    As of 8.3.0/8.3.1, networks that were entered in General Firewall Configuration -> Operational -> Generically Forwarded Networks are no longer supported and will be removed. Networks that are configured in this list will no longer be forwarded by the firewall after updating to release 8.3.0 or higher. You must configure a forwarding firewall service with corresponding rules to have this functionality.

  • Protocol 254/FW compression
    Firewall-to-Firewall compression has been discontinued and is no longer configurable. Traffic that was previously configured to use FW-2-FW compression will now be transported uncompressed.

Features that Will Become Obsolete in an Upcoming Release

  • FWAudit

  • WAN Optimization

  • CloudGen Firewall Web UI

Precautionary Security Measures for Control Centers

If you have a Control Center deployed with the CC wizard and there is no ECDSA CC SSH key configured at CC Identity, Barracuda Networks recommends the following to avoid possible security risks:

  1. Manually create a new ECDSA "CC SSH key"

  2. Create a legacy CC SSH key with more than 512 bits

Important Note for Users Wanting to Upgrade from Firmware Release 8.2.2

As of February 6, 2023, you can now upgrade from firmware release 8.2.2 to firmware release 8.3.1. This upgrade can be installed both on CloudGen Firewalls and on Control Centers. However, as this is a special upgrade, there are two different methods of how you must perform it depending on the type of your appliance.

For more information on how to upgrade from firmware release 8.2.2 to 8.3.1, see 8.3.1 Migration Notes.

Use the Appropriate Firewall Admin Release

Generally, Barracuda Networks recommends using the latest version of Firewall Admin for a new firmware release.

As of the public availability of this firmware 8.3.1, Barracuda Networks recommends using at least Firewall Admin version 8.3.1-64. You can download this version here: https://dlportal.barracudanetworks.com/#/packages/5466/FirewallAdmin_8.3.1-64.exe.

Release Notes

Firmware version 8.3.1 is a minor release.

Before installing the new firmware version:

Do not manually reboot your system at any time during the update unless otherwise instructed by Barracuda Networks Technical Support. Upgrading can take up to 60 minutes.

IMPORTANT Note for Hotfix-1083

SAML/ADFS Authentication also relies on the parameter Session Cookie Lifetime and can be configured at Box > Infrastructure Service > Authentication Service > SAML/ADFS Authentication, in section SAML Configuration. Switch to Advanced Mode in the left menu area, and click CONFIGURATION MODE to get access to this parameter.

If you have SAML/ADFS Authentication enabled and the value for the parameter Session Cookie Lifetime is not 0, you must set the value to 0 after installing hotfix-1083.
