For more information on how to use OTP, see
- How to Configure Multi-Factor Authentication Using Time-based One-time Password (TOTP)
- How to Self-Enroll for Time-Based One-Time Passwords (TOTP) using the Simple TOTP Web Portal
Configuration Template Manager
Configuration Templates are a new Control Center tool for creating and maintaining configurations for firewalls and SCs, with a special focus on scalability and automation. The tool is available for the Control Center and CG firewalls starting with release 8.2.
Configuration Templates allow you to do the following:
- Manage common configuration information for deploying and managing large-scale configurations while providing maximum freedom to individually configure parameters. This makes it easy to distinguish similar configurations from each other.
For more information on the Configuration Template Manager, see Configuration Template Manager.
When configuring ATP Cloud Communication in CONFIGURATION > Configuration Tree > Box > Assigned Services > Virus Scanner > Virus Scanner Settings > ATP, the list for Region in the section ATP Cloud Communication now contains entries that offer a greater range of options for the region.
Control Center Admins
The user interface for Control Center administrators has been redesigned to provide a better overview.
If you experience transfer rate issues when connecting from an on-premises CloudGen firewall to the Google Cloud via a VPN TINA tunnel, please read the following to potentially resolve the problem:
- Because Google Cloud VPN does not support fragmenting of packets after the encapsulation, the maximal MTU size for VPN gateways must be set to 1460 bytes. Therefore, if you want to connect from an on-premises CloudGen Firewall to the Google Cloud via a VPN TINA tunnel, you must ensure that the standard MTU size on your firewall is set to 1390 Bytes, e.g., in CONFIGURATION > Configuration Tree > Box > Assigned Services > VPN > VPN Settings > Routed VPN.
- Some Internet providers regard port #691 as a 'lower port number' (because the port number is lower than 1024) and limit the maximal transfer speed on that port. Because Barracuda CloudGen Firewalls use port #691 for VPN TINA tunnels, connecting to the Google Cloud may result in a limited transfer speed, which negatively influences the flow of traffic through port #691.
Because this is not a generic problem caused by the firewall, Barracuda recommends as a workaround to shift traffic from such a speed-limited connection port to a port range above 1024, which is usually not limited in speed. For this, you must do the following:
- On the active side of the VPN tunnel, which is the CloudGen Firewall, create an access rule with a DstNAT for the host firewall that redirects traffic from port #691 to any valid/free port number above 1024 that provides higher speed transfers. For more information on how to create a DstNAT access rule, see How to Create a Destination NAT Access Rule.
- On the passive side of the VPN tunnel, create an access rule with an AppRedirect to shift traffic from your selected high-speed port back to the original port #691. For more information on how to create an AppRedirect access rule, see How to Create an App Redirect Access Rule.
Hostname List for Barracuda Services
Access to hosts and domains in the Barracuda Cloud is required for the proper operation of a Barracuda CloudGen Firewall or Control Center. The hostname list has been updated to reflect the newest values for domains and their associated IP addresses and port numbers.
For more information on the updated hostname list, see Best Practice - Hostname List for Barracuda Online Services.
New Barracuda Health Monitoring System Goes Live
Think Customer and Drive Innovation are core values of Barracuda Networks. The better we understand how our solutions are used, the better we can enhance our services and proactively improve product quality. A big step in this direction is provided by the analysis of appliance health data and associated contextual telemetry information that the newer Barracuda CloudGen Firewall appliances can provide. With the current firmware release this is now active by default.
The configuration change is automatically applied to all new installations and upgrades of previous firmware versions. The status of Barracuda health monitoring is displayed in the Dashboard view in the Status window for stand-alone firewalls and on the Firewall Control Center under Control > Status Map.
REST API Enhancements
The REST API has been updated and is now in sync with the newest features of firmware release 8.2.0.
Tufin SecureTrack is a firewall management solution that enables security, compliance, and connectivity visualization of Enterprise IT across multi-vendor firewall environments and cloud platforms. SecureTrack provides insights into network connectivity and security policy changes and can also alert for potential new security risks.
With the start of firmware release 8.2, the CloudGen Firewall supports integration with Tufin SecureTrack.
For more information on how the Barracuda CloudGen Firewall integrates with Tufin SecureTrack, see TUFIN Integration API Service.
VPN Forward Error Correction
The transmission of interactive and streaming content can sometimes lead to data loss during transmission. If sufficient bandwidth is present, additional forward-error-correction (FEC) packets can be sent so that lost payload can be recovered.
Because FEC requires a special CPU command set, known as the SSSE3 extension, virtual hardware also depends on the availability of this extension. Therefore, it is necessary to upgrade the virtual hardware to make use of this special feature on ESXi hypervisors.
For more information on upgrading virtual hardware, see the migration instructions for 8.2.0 in the 8.2.0 Migration Notes.
Switches for Logging Special VPN Information
Two new switches have been added to CONFIGURATION > Configuration Tree > Box > Assigned Services > VPN > VPN Settings:
- Log VPN user accounting: If set to On, this option creates a log entry for every user log-in and log-off for a client-to-site connection.
- Log SDWAN: If set to On, the firewall stores the Min/Avg/Max value of the throughput every 5 minutes.

- After migrating from the 3-layer server-service architecture to the new 2-layer service architecture, IKE tunnels work as expected. [BNNGF-71419]
- The VPN client for NAC 5.2.1 no longer crashes if tunnel compression is active. [BNNGF-71648]
- IPsec tunnels are now stable and work as expected. [BNNGF-72561]
- The triple-DES encryption will no longer be available if VPN is operating in FIPS 140-2 mode. [BNNGF-73018]
- IKEv1 tunnels are now stable and work as expected. [BNNGF-73187]
- DynMesh tunnels are now completely removed when no longer needed. [BNNGF-73356]
- The signal handler of the VPN server now works as expected and is no longer terminated unexpectedly in certain situations. [BNNGF-73384]
- Azure – OMS is currently not supported on CC-managed boxes.
- Currently, no RCS information is logged for Named Networks. [BNNGF-47097]
Barracuda Firewall Admin – Copying and pasting an access rule with an explicitly named network does not copy the named network structure. [BNNGF-48588]
- Barracuda Firewall Admin – FW Admin 8.x fails to configure DNS 7.x correctly. [BNNGF-77636]
- Barracuda OS – Event Mail Notification is not working after the update to 8.2.0. [BNNGF-76327]
- 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.
- DNS – Although the underscore character ('_') may be used for DNS domain names in the CGF user interface, the character is not processed correctly by the underlying BIND system. [BNNGF-69225]
It is not recommended to use the underscore character ('_').
- Firewall – Inspecting traffic for QUIC / UDP 443 is currently not supported. [BNNGF-74540]
- Firewall – If there are multiple custom objects filtering for the same content, matching will fail. [BNNGF-76562]
- "vmxnet" driver version 2 is no longer supported. Before updating, you must change to, for example, vmxnet3.
- The migration wizard to 2-layer architecture for a managed box on a CC does not update the status map accordingly. A workaround using conftool is available.
- Installing a box with box.pca and/or re-deploying config via /opt/phion/update/box.pca does not work. [BNNGF-77829]
- SSLVPN – RDP connections can terminate after an unspecified amount of time and need to be re-established by the user. In some cases, connections cannot be re-established at all.
For a workaround, manually restart the service on the CLI via
killall sslvpnsrvTo periodically restart via a cron job and/or script, use
/usr/bin/killall sslvpnsrvFor questions on how to implement automatic restart procedures, contact Barracuda Technical Support for assistance. [BNNGS-3761]
- VPN - If the firewall has hundreds of VPN tunnels established and the tunnels are either operating via a routed VPN or are "TCP and/or hybrid and/or IPsec tunnels", re-establishing these tunnels after a provider outage does not work. [BNNGF-73584]
