8.2.1 Release Notes

  • Last updated on

Before installing 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.


To keep our customers informed, the "Known Issues" list and the release of hotfixes resolving these known issues are now updated regularly. If there are intermediate updates to this release, the corresponding notes will be found in this info box.

Version 8.2.1 is a minor update firmware release.

What's New in Version 8.2.1

HA Auto-Pairing

You can activate the HA auto-pairing feature to turn two separate firewalls into an HA pair with a minimum effort in configuration.

For more information, see HA Auto-Pairing.

Consolidated Menu for Importing Certificates

All UI buttons with a context menu for importing certificates with the file ending .cer, .crt, and .pem have been consolidated into a single, common context menu item. The format conversions will be handled automatically in the background by Firewall Admin.

Known Issues

  • Barracuda Firewall Admin – FW Admin 8.x fails to configure DNS 7.x correctly.    [BNNGF-77636]
  • Barracuda OS – BGP routes do not come up after VPN restart.    [BNNGF-79770]
  • The learn-only mode for OSPF is not working as expected.    [BNNGF-65299]
  • Control Center – After configuration and activation of the SAML/ADFS authentication, the SP metadata is not set on the Control Center.     [BNNGF-76521]
    As a workaround, complete the following steps: 1. Connect to the box.  2. Configure SAML doing an Emergency Override.
  • Firewall – Inspecting traffic for QUIC / UDP 443 is currently not supported.    [BNNGF-74540]
