Some tasks require the use of client-server applications. The Barracuda SSL VPN Agent on the client established a secure tunnel to the Barracuda SSL VPN and then launches the application specified by the application resource. Application definitions are regularly updated with Energize Updates. There are two types of application resources:

Full application download

No preinstalled application is necessary. The download automatically starts when the application resource is started. These applications may be limited to just one platform. Some examples for full applications are:

  • PuTTY
  • UltraVNC
  • Firefox Portable

Configuration file download

For this type of application resource, the application must be preinstalled on the client system. The Barracuda SSL VPN starts the local application on the client and provides a configuration for the resource you want to access. Examples include:

  • Microsoft RDP client
  • RDP - RDesktop
  • Remote Desktop Client v2 for macOS
