What´s New in Version 7.2.2

Globally Configured Unique Server/Service Names

On a Control Center, server and service names can now be configured also globally as unique.

For more information, see How to Configure Virtual Servers.

Network Objects now Accepts IP Addresses and Hostnames

Network objects now accept IP addresses as well as hostnames and dresses or resolves a given hostname to its associated IP address.

For more information, see IP or Hostname Network Objects.

The use is limited to the CC and currently covers:

  • Configuration of destination hosts for syslog streaming.
  • Configuration of hostnames as proxy destination.
Event Notification for Unused Access Rules

The CloudGen Firewall now creates an event in case that an access rule has not been used for a given number of minutes. In case a network routing was configured wrong or network cables were patched wrong, this event will inform about traffic bypassing the firewall unexpectedly.

For more information, see Advanced Access Rule Settings and Security Events .

BRS

The Barracuda Reporting Server (BRS) is a hardware appliance purpose-built for rapidly generating reports while maintaining or improving the accuracy of reporting data. It also provides an aggregate view of data for customers with multiple connected devices.

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

Commandline PAR File Restore with CCDB

A command line tool called cctool has been implemented for backing up and restoring Control Center configurations including setups for FSCs.

For more information, see How to Backup and Restore CC Archive Par Files on the Command Line.

CloudGen Firewall and RSTP

RSTP on a CloudGen now creates events in case that the state of an RSTP link changes. This is useful for notifying administrators in case that links on the bridge change their state.

For more information, see Security Events .

Cloning Wizard

In the Control Center, cloning a box is now possible using a wizard.

For more information, see How to Add a New CloudGen Firewall to the Control Center.

Dynamic Firewall Rules

Administrators now can restrict enabling of dynamic firewall rules with time conditions.

For more information, see How to Restrict Enabling of Dynamic Firewall Rules.

Control Center Clustering

Control Centers can now be organised in a master to slave hierarchy.

For more information, see Control Centers in Master-to-Slave Relation

LED Status Improvements for Hotfixes

When installing a hotfix via USB during recovery, the firewall now indicates the status after the hotfix installation via its LEDs on the front panel.

Renaming of Clusters in the Control Center

It is now possible to add an individual description to the name of a cluster which will be displayed in the configuration tree of the Control Center.

Web UI for Virtual Appliances

The Web user interface is now also available for virtual appliances.

ATP on Small Appliances

Advanced Threat Pprotection (ATP) is now enabled on the F12 model where local virusscan is not possible due to resource restrictions. ATP provides full protection against viruses.

Active Bridging despite of Inactive Firewall

If configured, the bridge will now stay active even if the forwarding service is down.

Pool License Validity Improvement

Running release 7.2.2 or higher, services keep running with an additional grace of 24 hours after the pool license grace period has expired. The license keeps working, but configuration and updates are blocked.

Current Known Issues - General
  • Firewall – Copying access rules with enabled SSL Inspection from firewalls running firmware version 7.2.x to firewalls running firmware version 7.1.0 - 7.1.3 can have a negative impact on SSL Inspection on the destination system.
  • ATP – The "Scan first, then Delivery" option and SMTP-AUTH is not yet supported. [BNNGF-52992]
  • ATP – The "Scan first, then Delivery" option and using an MUA (eMail client) - NGFW - MTA is currently not supported. [BNNGF-52992]
  • ATP – The "Scan first, then Delivery" option and using BDAT (e.g. Microsoft Exchange servers may use that) is not yet supported. [BNNGF-52992]
  • ATP – The "Scan first, then Delivery" option with SMTP and VRF is not yet supported. [BNNGF-52992]
  • AWS-Cloud – Deploying AWS Auto Scaling clusters in the US-East-1 region currently fails to create an S3 bucket automatically. Create the bucket manually instead.]
  • Certificate Store – When referencing certificates in the Certificate Store from services like SSL Inspection, the reference counter in the Ref By column still shows 0. [BNNGF-50666] 
  • Control Center –  When a tunnel is deleted on a CC, the GTI tunnel is not automatically removed from the configuration. To work around this issue, perform a change in the VPN configuration on the affected firewall unit and activate the changes - The tunnel will then be removed along with the change.    [BNNGF-54752]
  • Network – Transferring data over VLAN interfaces configured on the switch port of CloudGen Firewall F180a or F280b fails due to inability of changing the MTU size. [BNNGF-46289]
  • Firewall Admin – Copy and paste of an access rule with explicit Named Network does not copy the Named Network structure. [BNNGF-48588]
  • Virtual Routing and Forwarding (VRF) – Actively sending unsolicited ARP messages does not work with VRF. [BNNGF-52654]
  • Virtual Routing and Forwarding (VRF) – Changing the ID of an active virtual router instance to another ID is currently not supported. Instead, see How to Delete a Virtual Router Instance and How to Configure and Activate a Virtual Router Instance with Hardware, Virtual, VLAN, or Bundled Interfaces.
  • Virtual Routing and Forwarding (VRF) – Changing the MTU size for VR instances is currently not working as expected. [BNNGF-53385]
  • Virtual Routing and Forwarding (VRF) – Configuration files for VR instances are currently not considered when moving PAR files between boxes. [BNNGF-53390]
Current Known Issues Related to the Web Interface for Cloud
  • Azure Cloud – In Azure, after switching from Firewall Admin to the web interface, the connection can become very slow or even time out. [BNNGF-49960]
  • Backup/Restore – For cloud instances, restoring configuration backups does not work on models except VFC8 model with BYOL.
