7.2.0 EA1 Release Notes

  • Last updated on

EA firmware is available to early adopters who wish to test the latest features from Barracuda Networks, or who have a specific need for early access to a new feature or fix that would be beneficial to your environment.

The 7.2.0 EA1 release will not be displayed in the dashboard element of NextGen Admin and will not be listed in the Control Center as a firmware update.

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. Upgrading can take up to 60 minutes. For assistance contact Barracuda Networks Technical Support.

For more information and a list of supported NextGen Firewall models, see 7.2.0 EA1 Migration Notes.

As of January 31, 2019, the first-generation ATP cloud services used by default with firmware versions 6.2.x, 7.0.x, 7.1.0, 7.1.1, and 7.2.0 will be discontinued. Firewalls using ATP must switch to the second-generation ATP cloud service, which is known as Barracuda Advanced Threat Protection (BATP).

For more information, see 7.2.0 EA1 Migration Notes.

What´s New in Version 7.2.0 EA1

SSL Inspection Policies

SSL Inspection decrypts both SSL and TLS connections so the firewall can allow Application Control features, such as the Virus Scanner and ATP, to scan traffic that would otherwise not be visible to the firewall service. Using SSL Inspection allows the admin to enforce SSL/TLS security at the firewall by blocking outdated ciphers or refusing connections attempting to use outdated SSL versions. For outbound SSL Inspection, the firewall can also handle SSL validation errors, depending on the SSL error policy assigned to the matching access rule of the SSL/TLS session. SSL Inspection is supported for Pass, Map, and Dst NAT access rules. Not supported are SSL connections that require client certificate authentication.

VPN Tab Traffic Intelligence Improvement

VPN tunnels using the TINA protocol now provide an option to monitor bandwidth and latency for two TINA transports simultaneously.

Volume-Based PAYG Image Available for AWS

A new AWS image is now available that includes a built-in PAYG license and reports consumed volume in MB/hour via an API provided by AWS.

For more information, see  How to Create an IAM Role for an F-Series Firewall in AWS,  Public Cloud Licensing Types and How to Deploy a Volume-Based (Metered) PAYG CloudGen Firewall image in AWS.

Web Interface

The web interface now supports the TINA protocol and access to the Public Cloud.

Hourly PAYG Images for Google Cloud

PAYG is now supported for Google Cloud.

For more information, see  Public Cloud.

NextGen Control Center in Google Cloud

The NextGen Control Center is now available for Google Cloud as a Bring Your Own License image.

For more information, see  Getting Started - Control Center for Public Cloud.

Cloud Information Element for Google Cloud

NextGen Admin now provides an information element for Google Cloud to be displayed in the dashboard.

Barracuda Reporting Server Integration

Streaming of reporting data to the Barracuda Reporting Server is now supported via syslog streaming.

For more information, see  Barracuda Reporting Server (BRS) Integration.

Named Networks for IPv6

It is now possible to create Named Networks for IPv6 networks.

For more information, see Named Networks.

REST API Improvements

REST API documentation is now available in a separate section. APIs have been added for Control Center, license activation, and modification of network objects. It is now possible to add and remove entries to/from network objects and to add and remove IP addresses to/from custom external objects.

For more information, see https://campus.barracuda.com/product/nextgenfirewallf/api

POP3 / POP3S Virus Scanning

For clients behind the firewall, it is now possible to scan mail traffic to SMTP and from POP3 servers in the Internet using the Virus Scanner and optional SSL Inspection.

For more information, see  How to Configure Virus Scanning in the Firewall for Outbound SMTP and POP3 Traffic .

Explicit Authentication Scheme in Username for Client-to-Site VPN Connections

VPN users can now use an authentication scheme that is appended to the username , e.g., @msad. The authentication scheme (e.g., @msad) with the prepended username (e.g., user1@domain.com) is used with the default authentication scheme acting as a fallback if the authentication scheme name is not present on the firewall. E.g., user1@msad1 or user2@domain.com@msad.

For more information, see  How to Configure a Client-to-Site VPN Group Policy.

Generic Network Objects

You can now use network objects to reference networks, IPv4 and IPv6 addresses, hostnames, geolocation objects, MAC addresses, or interfaces when you create access rules.

For more information, see Network Objects.

Log Viewer

Log Viewer now displays log files in a new format.

For more information, see  LOGS Tab.

SSL VPN Improvements: Single Sign-On and New Attributes for RDP Native App

The native SSL VPN app of the type RDP now also supports single sign-on for improved usability. In addition, it now also supports advanced RDP options for logon settings and connections, display settings (such as multi-screen support), local device and audio support, and connection performance settings.

For more information, see How to Configure SSL VPN Native App for RDP.

External Control Center Admins

External admins can now authenticate to a Control Center or to CC managed boxes using an external MSAD account that can be mapped to an administrator account on the Control Center. Therefore, the MSAD must be reachable.

For more information, see  How to Map Admins From User Groups of External Authentication Schemes.
