What's new in Version 8.0.4
Migrating the Old 3-Layer Server-Service Architecture to the New 2-Layer Assigned Services Architecture
With firmware version 8.0.4, you have the option to migrate the former 3-layer server-service architecture to the new 2-layer Assigned Services architecture. While this is optional in all 8.0.x releases, it will be mandatory in the next upcoming major release.
For Barracuda-only environments, setting up a site-to-site VPN tunnel has been greatly improved. The new AutoVPN feature provides robust VPN connections through TINA tunnels that are automatically set up with dynamic routing between local networks. AutoVPN is suited for creating multiple boxes in the cloud and connecting them with a TINA site-to-site VPN tunnel.
The automatic setup of VPN tunnels is initiated via the command-line interface (CLI) and REST API.
For more information, see AutoVPN for CloudGen Firewall Devices 8.0.1 or Higher.
Barracuda Control Center License Activation
When a Control Center is started for the first time, the CC Wizard will prompt you to enter a username and a password that will be used to automatically download licenses.
For more information, see Getting Started - Control Center.
Barracuda Firewall Insights
The Barracuda Reporting Server has been replaced by Barracuda Firewall Insights. Barracuda Firewall Insights is an advanced reporting and analytics platform that ingests, aggregates, and analyzes data automatically from any CloudGen Firewall deployed across your organizational network, including public cloud deployments. Analytics by Firewall Insights provide actionable information for the entire WAN, including dynamic availability information on SD-WAN connections, transport data, security, and web and network traffic details.
For more information, see Firewall Insights.
IPv6 for Client-to-Site Payload
Client-to-Site VPN TINA tunnels now support the configuration of IPv6 client networks.
Microsoft Azure Market Place Improvements
The Microsoft Azure Marketplace supports the deployment of High Availability clusters. High Availability ensures that the services running on the CloudGen Firewall are always available even if one unit is unavailable. It is therefore highly recommended. The deployment of a CloudGen Firewall in Microsoft Azure is easy thanks to the web interface that guides you through the process.
Microsoft Azure Virtual WAN
The Barracuda CloudGen Firewall supports up to four Internet Service Provider (ISP) links to Microsoft Azure Virtual WAN. You must have a static IPv4 public IP address with similar bandwidth and latency. For each link, two active-active IPsec IKEv2 VPN tunnels are automatically created if you use automated connectivity. BGP multi-path routing is used to route the traffic, and the configuration of BGP multi-path routing is likewise set up automatically when using automated connectivity. The firewall learns path information as set by the Virtual WAN hub, which results in better path affinity. In addition, BGP-based load balancing and automatic path failover are used for the best connection results.
For more information, see Azure Virtual WAN.
Multi-Factor Authentication with Time-Based One-Time Password (TOTP)
With the release of firmware version 8.0.1, the Barracuda CloudGen Firewall supports multi-factor authentication for user accounts on an individual basis, using a Time-based One-time Password (TOTP) as a secondary authentication method. Multi-factor authentication can be enabled for client-to-site VPN (TINA protocol only), SSL VPN, CudaLaunch, and the Barracuda VPN Client for Windows. Multi-factor authentication using TOTP requires an Advanced Remote Access subscription.
For more information, see How to Configure Multi-Factor Authentication Using Time-based One-time Password (TOTP).
NTP Servers for the Barracuda Zones
The NTP default configuration now displays 4 NTP servers for the Barracuda zone in CONFIGURATION > Configuration Tree > Box > Administrative Settings.
New DNS User Interface and Advanced DNS Features
The DNS service has been refactored and now offers a new user interface. This user interface is now tightly incorporated into new features that extend the DNS by various advanced options. The feature set of the new DNS service now includes:
- Stand-alone and distributed DNS service
- Master / Slave / Forward DNS zones
- Split DNS
- Health probing
Replacement of Virtual Servers by a New 2-Layer Architecture
The former 3-layer server-service architecture has been replaced by a 2-layer architecture in which services are now operated on top of the box layer. With firmware 8.0.1, services are subordinated to the Assigned Services node and allow a simpler administration of services and reduce error-prone issues by limiting services to run only on the box they are initially created on.
Optimized Command-Line Tool for Configuring an HA Pair of Firewalls in the Cloud
The command-line tool
create-dha for creating an HA pair of firewalls in the cloud has been optimized. The command no longer requires you to configure the parameter of a netmask because both firewalls must be configured in a subnet of the same size.
REST API Extensions
- REST calls for logins, logout, and authentication for endpoints
- REST for all common access rule operations: create / delete / list / change
- REST calls for network objects (stand-alone + CC (global cluster firewall objects))
- REST calls for service objects (CC + stand-alone)
- REST calls for enabling and activating IPS
- REST calls to allow you to manage box administrators
- REST calls to allow you to manage tokens
- CLI tool to enable REST by default on cloud firewalls (place in user data)
For more information, see https://campus.barracuda.com/product/cloudgenfirewall/api/8.0
SNMP now provides the option to monitor license status, the number of days until a license expires, and the current number of protected IPs.
Also, there is now the option to monitor certificates and their expiration date.
The new TOTP portal provides self-enrollment and self-service of the TOTP authentication scheme.
SSL VPN resources can now be configured as dynamic apps. If configured as a dynamic app, Super Users can enable, disable, or time-enable a resource. Dynamic access can be configured for web apps, native apps, generic tunnels, and network places.
For more information, see SSL VPN.
Usage of DHCP on a VLAN Interface
Requesting an IP address from a DHCP server for a VLAN interface is supported by a feature called Header Reordering and can be found in the VLANs Window accessible in CONFIGURATION > Configuration Tree > Network > Virtual LANs.
For correct usage of the user interface item Header Reordering, see the following table:
|User Action||User Interface Item||Description|
|Default state: header reordering is off.||No header reordering is done for DHCP on a VLAN interface.|
|Select the check box in case the assignment of |
an IP address from a DHCP server fails.
|Header reordering for DHCP on a VLAN interface is now activated.|
VPN IPv6 Payloads
With the exception of SD-WAN, IPv6 payloads in VPN tunnels are supported and now work for TINA site-to-site and client-to-site tunnels.
