Installation of Tunnelblick on Mac (OpenVPN)

It is possible to form an encrypted remote connection from your home computer to the servers of the University of Helsinki. A VPN connection is also useful in unencrypted networks. If you wish to access your home directory (i.e. the Z drive) or group directories (P drive) from your home computer, first act according to these instructions and then open the instructions for the remote use of home and group directory

MacOS Big Sur 11.3 was released on November 12th, 2020. Centrally maintained University of Helsinki computers will be updated according to a schedule determined after testing.
New computers will be with macOS Big Sur installed.

Increased capacity

The University of Helsinki IT Center has increased the capacity of the OpenVPN service by adding a new uh-vpn-helsinkifi-only connection

Use the uh-vpn-helsinkifi-only (or HY-TUN) connection, if you work in your home network or another trusted network: 

  •   Only necessary traffic is transferred via the university network (e.g. home directories, Efecte, SAP)  
  •   Less traffic load on the university network 

Use the uh-vpn-allroute (or HY-VPN) connection, if you are in another network, e.g. a café or a hotel 

  •   All traffic is transferred securely through the university network 
  •   More traffic load on the university network 

For the university computer you can install Tunnelblick from Managed Software Center (see instructions)

Installing Tunnelblick and HY-VPN for the home computer

Extract the dmg-file you just downloaded and copy Tunnelblick.app to the Applications folder.

Download the configuration profile files

When asking please enter the macOS administrator password.

Select Only Me (VPN settings only installed on the user account which is currently logged in) or, preferably, All Users (all user accounts have access to the VPN connection).

Tunnelblick creates a Tunnelblick folder in the Application Support folder where the configuration files are copied. The Only Me option creates a folder in the Library folder of the home folder and an All Users Macintosh HD in the Library folder.

Forming an encrypted connection

• Open the Applications folder and click on the Tunnelblick icon.
• A tunnel icon appears in the menu row in the top right corner of the screen. Click on the icon and select Connect uh-vpn-allroute or Connect uh-vpn-helsinkifi-only.

The software will ask for the user name and password you use in the university's services. After you have entered them, the software initiates the connection.

In future, you can form an encrypted connection by repeating the last three stages.

Disconnecting the connection

Click Tunnelblick icon and select Disconnect connection name  

Error situations

  • You may have encountered a new security feature in High Sierra and higher which restricts the loading of kexts (system extensions). Read more from Tunnelblick's site.
