  • Last updated on

Please Read Before Upgrading

Before installing the new firmware version, back up your configuration and read all of the release notes that apply to the versions that are more current than the version that is running on your system.

Do not manually reboot your system at any time while the update is in process, unless otherwise instructed by Barracuda Networks Technical Support.

If the process takes longer, please contact Barracuda Networks Technical Support for further assistance.

What's New in Barracuda Firewall Version 6.7.0.022

Application-Based Link Selection

Application-based connection objects allow you to select the Internet connection based on the application. Application-based link polices can be defined for individual applications or application categories. Traffic that does not match one of these policies is sent using the default connection object.

For more information, see Application Based Connection Objects.

Certificate Manager

The Barracuda Firewall uses the Certificate Manager as a central repository to manage all X.509 certificates on the device. You can create self-signed certificates or upload your own certificates. All certificates are available for all Barracuda Firewall services, as long as they meet the requirements for that service.

For more information, see How to Use and Manage Certificates with the Certificate Manager.

Email Notification

The Barracuda Firewall can alert the administrator of important system events by sending notification emails. You can configure a notification email policy for each event. To limit the number of emails for frequently occurring events, you can define up to three thresholds. Thus, the administrator will receive an email only when the number of events exceeds the threshold set in the timespan. The following events can trigger email notifications:

For more information, see How to Configure Email Notifications.

Destination NAT Load Balancing

DNAT_releaseNotes.png

To redirect to more than one server in cycle (round robin) or fallback mode, you can enter multiple IP addresses or use a network object containing multiple IP addresses for DNAT access rules. It is also possible to redirect to a different port by appending the port after the IP address.

For more information, see Firewall Rules and  Example - Configuring a DNAT Access Rule.

Inline Editing of Firewall Objects
Barracuda Firewall firmware 6.7.0 adds the option of editing or creating objects directly in the UI element they are referenced from. For example, you can now create a network object in a second popover when creating an access rule without having to break the workflow.
Usability Improvements for DHCP Server Configuration

The DHCP server configuration has been reworked to improve useability. The DHCP server subnet list now also shows which port is used by the DHCP subnet.

Authoritative DNS Server Improvements

The DNS server now allows you to distinguish between internal, external, and combined zones on a per-domain basis and automatically creates PTR records when creating A records.

For more information, see Authoritative and Caching DNS.

VPN Split Tunnel Mode

Enabling the split tunnel mode for a Client-to-Site VPN allows only the client access to the networks published for the Client-to-Site VPN. This feature is available only for Windows clients using the full-featured Barracuda Network Access Client.

SSL VPN Mobile Portal

The Barracuda Firewall SSL VPN mobile portal provides a user-friendly interface with a service bar where users can launch available web resources that have been made accessible by the Barracuda Firewall. Users can navigate through the resources and add shortcuts to a favorites list.The Barracuda Firewall SSL VPN mobile portal supports most commonly used devices, e.g., Apple iOS, Android and Blackberry.

For more information, see SSL VPN for the Barracuda NextGen Firewall X, Mobile Portal User Guide and Supported Mobile Devices.

Local Disk Backup and Restore

The Barracuda Firewall now automatically creates up to 24 hourly backups directly on the local disk of the unit. These backups can be restored directly via Web UI or from the recovery console.

For more information, see How to Backup and Restore the Barracuda NextGen Firewall X.
