Firewall Secure Connector Release Notes

  • Last updated on

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. For assistance, contact Barracuda Networks Technical Support.

FSC 2.0.x firmware supports Firewall Secure Connectors 2.x only. Installation on FSC1 appliances is not possible

FSC 2.0.x requires a Barracuda Firewall Control Center 7.2.3 + HF898 or higher.

Installing Firewall Secure Connector firmware version 2.0.5 requires migration of the Control Center Secure Connector Editor AFTER updating the Firewall Secure Connectors. This operation can not be reverted.

  • After migration to SC Release 2.0, the editor only supports Secure Connectors 1.x with firmware versions 1.1.5 and higher.
  • After migration to SC Release 2.0, the editor only supports Secure Connectors 2.x with firmware versions 2.0.5 and higher.

To migrate the editor, lock the editor configuration on your Firewall Control Center and click Migrate SC Release

What´s New in FSC Version 2.0.5

Additional LAN Modes

It is now possible to choose from three different LAN modes for the Secure Connector.

  • Switch mode - Combines all available LAN ports to a network switch group.
  • 2 Port Mode - Combines LAN2 and LAN3 to a network switch group. LAN1 can be configured individually.
  • 3 Port Mode - All available LAN ports can be configured individually.
Passive Link Probing for Link Selection

It is now possible to configure passive link probing as additional option of the Link Selection feature. Enabling Passive Probing enables probing of the first configured VPN IP address and disables probing of explicit probing targets. Passive Probing does not support UDP Mode of VPN tunnels.

New WAN Probing Options

It is now possible to configure additional WAN Probing options via ICMP, DNS, or both.

What´s New in FSC Version 1.1.0

FSC Containers

The Secure Connector running firmware 1.1.0 or higher can now run a single LXC container. The container is distributed and installed via the firmware update page on the Control Center.

For more information, see FSC Container.

Network Mapping Support

It is now possible separate data and management networks for the FSC. It is also possible to map the network behind the FSC to an automatically or manually mapped FSC data network. This allows you to use identical network configurations for each FSC, while still retaining a unique subnet for each location.

For more information, see How to Add a Secure Connector Configuration.
