For detailed information on the fixes and enhancements that are included in Barracuda Load Balancer ADC version 5.3, see:

What's New in Version 5.2

SSL Enhancements: Perfect Forward Secrecy (PFS) with ECDSA and RSA certificates and associated ciphers are now supported. The key exchange mechanism supported is Elliptic Curve DHE. These SSL enhancements are increasingly relevant in a post-Snowden world. With PFS, communications intercepted today can never be decrypted, even far into the future, due to the ephemeral nature of the PFS scheme. You can also customize backed SSL, including SNI extensions in the TLS header if the server requires this to be enabled. Supports Certificate Revocation List (CRL) and OCSP validation for client certificates. And supports Intel QuickAssist Technology for SSL acceleration in the Barracuda Load Balancer ADC 840 and above.

Traffic Management Enhancement: The Redirect Rule feature is now supported in the Barracuda Load Balancer ADC 340 and 440.

Load Balancer Migration Enhancement: You can now configure the WAN IP address, network mask, and gateway when restoring the Barracuda Load Balancer 4.x backup file to the Barracuda Load Balancer ADC

For detailed information on the fixes and enhancements that are included in Barracuda Load Balancer ADC version 5.2, see:

What's New in Version 5.1

Authentication and Authorization: Barracuda Load Balancer ADC models 540 and above can be integrated with an external authentication server for client authentication. LDAP, RADIUS and Kerberos authentication protocols are supported. You can create authorization policies that control access by authenticated users to web applications.

Application Security: The Application Security subscription, which adds Layer 7 security to your existing HTTP-, HTTPS-, FTP- or FTPS-based applications, is being made available at no charge to all ADC customers on models 540 and above. Configure security policies using the pages under the SECURITY tab.

Support for Barracuda Load Balancer Configuration: You can restore backup files from a Barracuda Load Balancer to a new ADC system.

Networking: Policy-based routing to route packets on a specific interface. You can add policy-based routing rules on the  NETWORK > Routes  page.

User Interface
  • The BASIC > Services page makes it easier to add, edit, and view services and servers. You can view and update every option when you add a service or a server. If you have similar services, you can use the settings of one service as a starting point when creating a new service. And, as before, you can view the status of all services and real servers at a glance.
  • The BASIC > Status and SECURITY > Security Policies pages also have a new layout.
  • The web interface has a new color scheme and improved look and feel.
  • An Instant SSL service (that redirects an HTTP connection to an HTTPS service) appears as only one service in the user interface. An Instant SSL service includes both the service port and the redirect port.
