General

TeamViewer has a built-in VPN service that allows you to connect to a device to share windows file shares and to share printers.

What does VPN mean?

Virtual private network (VPN) is a network technology that seamlessly extends an intranet and its resources across the globe using public networks such as the Internet.

This is achieved by the creation of a secure data tunnel or virtual point-to-point access between the host and the client. Once the connection is established, data is sent and received with the same security, functionality, and management policies as if the systems were in the same network location.

 

The way TeamViewer VPN works

TeamViewer VPN is a one-to-one connection between two computers. TeamViewer will use a TeamViewer connection (handled as a remote connection) to establish a VPN with IP-addresses which are addicted to the involved TeamViewer IDs.

The VPN service is not like your standard VPN, for example, Private Internet Access (PIA).

Our service acts more like a VLAN as the machines are placed into a virtual private network so that the devices think they are in the same network. Whereas, PIA takes your traffic and forwards it from the country server that you are connected to.

For the VPN to work, a VPN driver must be installed on both sides and can either be started during a remote control connection or on its own from within the TeamViewer settings.

 

How to install the VPN driver

You can install the VPN driver easily by clicking in your TeamViewer fullversion on Extras --> Options --> Advanced -->Click  Show advanced options --> Under Advanced network settings --> Install VPN driver --> click Install.

Note: You will need administrative rights on the device to install the VPN driver.

Use cases for TeamViewer VPN

Here are some example use cases for which TeamViewer VPN can be used:

  • Print documents on an enabled printer connected to the remote computer.
  • Run applications locally on your machine that accesses a remote database by setting up a VPN connection to the remote database server (e. g., for home office).
  • Give external participants access to devices (e. g. hard drives or USB sticks) connected to the remote computer.

 

VPN dialog box options

Once you are connected to the remote computer via VPN, within this VPN TeamViewer window, the VPN-TeamViewer dialog box will open up.

Set up TeamViewer VPN with the following options:

  • In the case of multiple simultaneous VPN connections, you can select the required connection from the Active VPN Connection drop-down list . The details and available actions for this connection are displayed in the dialog box.
  • Click the Close connection button to close the selected connection.
  • The Status area shows the assigned VPN IP addresses of both computers. Once assigned, the VPN IP address will stay the same. The amount of data transmitted is also shown.
  • The Share files via Explorer button opens Windows Explorer, giving you access to the remote file system. If folders on the remote computer are shared via the local network, you will be able to access them and delete, copy or move files as needed. Please note that you may need to authenticate yourself on the remote computer.
  • The Test ping button sends a ping signal to the remote computer. This lets you check whether a connection has been established successfully.

Note: You do not need a VPN connection to control your partner's computer remotely or transfer files using TeamViewer.

Note: If you connect your local computer to the remote computer via TeamViewer VPN, only those two computers will be linked together in a virtual private network. No other computers in the LAN of either computer will be accessible.

Note: In case the TeamViewer VPN driver is not yet installed, the VPN option button is not visible within the main TeamViewer window!

 

Troubleshooting for TeamViewer VPN

In case you are experiencing issues with TeamViewer VPN, our technical support put together a list of recommended troubleshooting below.

Important:
If none of the below troubleshooting-steps resolve the issue you are experiencing, there might be an incompatibility between the VPN driver and the operating system.

Please understand that the TeamViewer Support can not assist in these cases.

 

Reinstallation of TeamViewer and VPN driver

Hint: If possible, do the reinstallation on both sides of the connection.

Please follow the below steps for the reinstallation.

  1. Uninstall the TeamViewer VPN driver via Extras --> Options --> Advanced -->Click  Show advanced options --> Under Advanced network settings --> Install VPN driver --> click Uninstall..
  2. Uninstall TeamViewer
  3. Download TeamViewer from our website and install it.
  4. Install the VPN driver and try the connection again

 

Manual installation of the VPN driver

Windows makes it possible to install drivers without using the software. That allows you to install the TeamViewer VPN driver.

You will find the file needed for this in the installation folder of TeamViewer: 

C:\Program Files\TeamViewer\x64\ TeamViewerVPN.inf

 

For the manual installation please follow the below steps:

  1. Press Windows-Key + R and enter hdwwiz.cpl
  2. Click in the Window and then on Action --> Add legacy hardware --> Next
  3. Select Install the hardware that I manually select from a list (Advanced) --> Next
  4. Select Network adapters --> Next
  5. Click on Have Disk… --> Browse and select the TeamViewerVPN.inf --> Open --> OK
  6. Click on Next until the installation is finished
  7. Now please try the VPN connection again

 

Forcing TeamViewer to use Port 443

In case the steps above did not work for you, please create the following registry key to force TeamViewer to use Port 443:

32 bit:

HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer

64 bit:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TeamViewer

DWORD registry key AllowedConnectionProtocols and add the value 4.

Afterward, restart the TeamViewer service via services.msc on both Computers and try the connection again.

Important:
Only use this registry entry for this case (or when recommended by the TeamViewer Support) to avoid unwanted side effects like TeamViewer slowing down. 

 

Test Ping troubleshooting

In case the test ping does not work, please follow these steps:

  • Open your file explorer
  • Enter the following string in the address bar on your device and change 123.123.123.123 to the IP address shown in the dialog box in the box IP of Partner
    \\123.123.123.123\c$
  • If you can now see the C: drive from the remote side, the connection is working
