What´s New in Version 7.1.1

VPN Apps in the SSL VPN


VPN Apps for the SSL VPN are used to allow users to connect to internal web applications not suitable for SSL VPN Web Apps or native apps. CudaLaunch transparently opens a client-to-site VPN tunnel and then opens the resource in the default browser. VPN Apps are available on Windows, iOS, and Android clients through the CudaLaunch app. 

For more information, see SSL VPN VPN Apps

Detect and Block DNS Tunnels


DNS tunnels make use of TXT or NULL DNS records to tunnel traffic through DNS queries and responses. The NextGen Firewall can now detect and block DNS tunneling via protocol object in Block or Deny application rules.

For more information, see How to Create a Protocol Object and How to Create an Application Rule.

Azure Stack Support


The NextGen Firewall and Control Center can now be deployed in your Azure Stack environment. You can deploy either by making the standard Azure Marketplace images available for your users, or by uploading and then deploying the BYOL VHD disk images from the Barracuda Download portal.

For more information, see Microsoft Azure Deployment and How to Upload Azure VHD Images for User Defined Images using ARM.

New Rugged Hardware Model F183R


Barracuda released a new ruggedized industrial appliance: The 7-port F183R with two fiber ports.

For more information, see F183R (Rugged).

New Hardware Model F183



The F183 is a desktop appliance with 6 gigabit and 2 fiber ports.

For more information, see F180 and F183 Revision A.
