How to Configure a Tunneled Web App

  • Last updated on

Create tunneled Web Apps to allow SSL VPN users to access web-based internal applications through an SSL tunnel created by CudaLaunch. The client then connects to a dynamically generated port on the loopback interface (e.g., 127.0.0.1:7324). CudaLaunch forwards the web traffic through the SSL tunnel to the SSL VPN service and the web server behind it. To use tunneled Web Apps, you must have a Remote Access Premium subscription.

Before You Begin

Enable the SSL VPN service and CudaLaunch. For more information, see How to Configure the SSL VPN Service.

Configure a Tunneled Web App

  1. Go to VPN > SSL VPN.
  2. Click the Resources tab.
  3. In the Tunneled Web Apps section, click Add Tunneled Web App. The Add Tunneled Web App window opens.
  4. Set Enable to Yes.
  5. (optional) Click Browse to upload a PNG file for the web portal. It must be less than 30 kB and no larger than 80x80 pixels.
  6. Enter the visible Name for the Web App. This is the name used in the SSL VPN portal for this Web App.
  7. Enter the IP address or hostname of the Web Server Host.
  8. Enter Web Server Port the host listens on.
  9. In the Client Loopback TCP Port field, enter the client loopback TCP port number for the tunnel to enable tunneling of application data to the user's localhost IP address 127.0.0.1:7000. To use a random port, enter 0 (default).
  10. Select the type of the tunnel from the Protocol drop-down list.

  11. (optional) To restrict access to the Web App by user group, remove the * entry in the Allowed User Groups list. Enter the user groups that can access the Web App, and click + after each entry. If no groups are added, the Web App cannot be accessed. Use question marks (?) and asterisks (*) as wildcard characters.
  12. Click Save.
