Frequently Asked Questions

What is the Barracuda Firewall?

The Barracuda Firewall is the next-generation firewall that delivers advanced features without reducing performance. Malware protection and content filtering takes place in the cloud, so network resources are not affected. Dynamic link balancing and traffic shaping keeps things running smoothly even while performing complex application control and policy enforcement. By aggregating and load-balancing multiple uplinks (e.g., MPLS, T1, DSL, 3G) with automatic and seamless failover, the Barracuda Firewall ensures users and applications have uninterrupted access to cloud applications and resources. The Barracuda Firewall is the most reliable and cost-effective network security and connectivity solution available for smaller and mid-sized organizations.

Does the Barracuda Firewall involve any sort of user fees?

No. There is no limitation on number of users or numbers of protected IP’s. All Barracuda Firewall models also include a license to an unlimited number of VPN clients.

What are Barracuda Firewall’s cloud-enabled capabilities?

Cloud-based content filtering delivers advanced security against today’s web-based threats without impacting network and application performance. By offloading processor-intensive content filtering and malware protection to the cloud, the Barracuda Firewall minimizes the demand placed on network resources to ensure optimal performance. 

Cloud integration for management and malware protection gives the Barracuda Firewall the elasticity to provision just the right combination of resources to meet your needs. As needs evolve and business grows, scaling cloud-based resources as needed is transparent and automatic.

Accessible via web browser or mobile app, the intuitive cloud-based management portal delivers truly flexible anytime/anywhere management.

What is Application Control?

Application identification techniques in traditional firewalls rely on basic technology features like URL, destination IP address, or TCP port / protocol definitions. Unfortunately, this doesn’t help administrators determine what applications users are accessing on their network.

The Barracuda Firewall uses Application Control to identify and enforce policies on applications that may masquerade their traffic as “safe” protocols such as HTTP. When reviewing an application log file, administrators can see what types of applications are seeking access to the Internet, such as peer-to-peer sharing applications, Skype, YouTube, and much more.

The Barracuda Firewall integrates application control into its core firewall functions, enabling enforcement of policies based on user ID, security policy, location, and time of day. Policy actions can include blocking, allowing, throttling, or even enabling or disabling of specific application features.

Can the Barracuda Firewall provide VPN tunnels to other firewalls or routers?

Yes, in most cases, you can create VPN tunnels from the Barracuda Firewall to other firewalls and routers. The VPN engine of the Barracuda Firewall is compatible with a wide variety of other router and firewall vendors. If the other endpoint VPN device is also certified for basic interoperability by VPNC, it can almost be guaranteed that there will be a way to connect these devices via a site-to-site VPN tunnel.

Is there a way to centrally manage multiple Barracuda Firewalls?

Yes. Administrators can centrally manage multiple Barracuda Firewalls via the Barracuda Cloud Control portal at no additional cost.

What is the difference the Between Barracuda Firewall and the Barracuda NG Firewall?

The Barracuda Firewall is developed to provide advanced application technology to the SMB and mid-tier customer base. To accomplish this, the Barracuda Firewall provides an easy-to-use web-based interface with intelligent defaults and cloud-based central management hosted by Barracuda Networks. The Barracuda Firewall is available in hardware configurations with up to 5 Gbps data throughput and up to 8 ports. As a result, the Barracuda Firewall is recommended for organizations with up to 10 locations. The Barracuda NG Firewall is a dedicated NG Firewall for large enterprise deployment. Typical requirements include support for several thousand remote locations, data throughput requirements of 20 Gbps or more and high port-density needs. Management of the Barracuda NG Firewall is accomplished via a Windows executable, while central management of multiple Barracuda NG Firewalls is accomplished via the Barracuda NG Control Center.

What user authentication methods are supported?
