Launching Resources

The Apps tab contains all the web resources. To launch a resource from the Apps screen, click the icon associated with it. Web app resources are launched using the default browser of the operating system.


The web resource launches in a new tab in your network browser, and you are redirected to the application page.

VPN Connections

The VPN Connections tab contains the VPN group policies configured by the admin for CudaLaunch. The Barracuda Network Access or VPN Client must be installed on the client to be able to start the VPN connection in CudaLaunch. To connect to the client-to-site VPN, click the VPN Group policy.



Native Apps

When launching native apps such as RDP, CudaLaunch automatically establishes a tunnel in the background and launches the app in a new browser tab.




Generic tunnels are used to tunnel TCP connections for client/server applications.

Click the Tunnels tab. Click one of the generic tunnel profiles that are made available by the admin.


The client connects to a port on the interface. Use the local IP address and port number in the locally installed app.


Network Places

Network places provide remote access to corporate file shares made available by the admin. The Folders tab allows you to browse network shares and to rename, delete, retrieve, and upload files.

Click the Folders tab. Click the 'forward' arrow icons to navigate through the folders and files.


  To launch a resource from the Folders screen, click the icon associated with it. When prompted for attributes, enter username and password, and click Continue.


Network places are launched using the default browser of the operating system.

To remove a resource from the favorites list, click the Favorites tab and then click the trash can symbol.

Dynamic Firewall Rules

These pages display all available dynamic rule categories with the rules that have been configured in the F-Series SSL-VPN Dynamic Firewall Rules configuration.
