9.0.3 Release Notes

  • Last updated on

As the CloudGen Firewall has evolved over the years with its increasing number of features, the Release Notes articles have grown accordingly. This, in turn, has also added greatly to the number of entries in the menu column.

To make the Release Notes articles easier to read, they are now equipped with support elements that provide a better overview of all sections contained while making it easier to navigate between and inside these sections.

Each of these sections can be expanded and collapsed separately to show only what you are interested in. Simply click below a header line to expand or collapse a section.

Note that depending on a certain release, the sections can vary both in content and number.  In addition, a headline may be attributed by certain symbols with the following meaning:

red_warning_tiny.png Critical information to be considered.

yellow_warning_tiny.png Important information included in the section.

update_tiny.png Updated information available.

feature-related.png Product-related information, e.g., new features, solved bugs.

know_issues_tiny.png Product-related information that relates to known bugs.

Note that regular information boxes in blue are not explicitly marked in the headline but may still appear in a section.

Each section can be expanded individually for informational or printing purposes.

Using Special Characters when Creating a Section in the Forwarding Ruleset

After the update to 9.0.3, ‘-' is the only special character that is allowed to be used in firewall section names.

General and Maintenance Information for the 9.0.3 Release Notes 

Firmware version 9.0.3 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.

To keep our customers informed, the history of this Release Notes article, the "Known Issues" list (at the end of this article), and the release of hotfixes resolving these known issues are now updated regularly. If there are intermediate updates to this release, the corresponding notes can be found in this info box.

18.9.2024 – Release of firmware 9.0.3.

23.9.2024 – Hotix-1134 – The hotfix fixes a regression for TINA transports without a provider created in GTI. Those will be disabled after the CC is updated to 9.0.3. This hotfix only applies to Control Center boxes!
For more information, see https://dlportal.barracudanetworks.com/#/packages/5968/VPN-1134-9.0.3-226753162.tgz

11.11.2024 – Hotix-1134 – Proxy Startup. This hotfix addresses an issue where the HTTP Reverse Proxy terminated too early if a certain number of backend entries exceeded the given limit. With this hotfix, the HTTP Reverse Proxy is now granted 10 seconds to start up and to work as expected.

For more information, see https://dlportal.barracudanetworks.com/#/packages/6018/proxy-1135-9.0.3-230798194.tgz.

Recommendations and Prerequisites for Running Firmware Release 9.0.3

Use the Appropriate Firewall Admin Release

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

As of the public availability of firmware 9.0.3, Barracuda Networks recommends using at least Firewall Admin version 9.0.3. You can download this version here: https://dlportal.barracudanetworks.com/#/packages/5946/FirewallAdmin_9.0.3-49.exe

Unlike in firmware 9.0.0 where Firewall Admin 9.0 no longer displayed GTI for firmware versions earlier than 9.0, this limitation has been removed as of release 9.0.1. Firewall Admin now displays GTI for Control Centers < = 8.3.

However, because WANopt is no longer supported, note that Firewall Admin now ignores all WANopt settings from GTI regardless of the version.

Who Can Update to Firmware Release 9.0.3

Read the Migration Notes 9.0.3 before updating to firmware 9.0.3.

For more information on the migration process, see the article Migration Notes 9.0.3.
