| + | Use Tunnelblick version 4.0.1 or newer. There is no longer any need to downgrade the OpenSSL version. Those who have set OpenSSL to version 1.1.1w as a temporary solution should create a new VPN connection for Tunnelblick with a new certificate and a new configuration file following these instructions. To do this, start at step [[VPN_on_macOS#create_network_certificate | Generate network certificate]]. | ||
| + | </bootstrap_alert> | ||
| + | |||
| + | You need VPN (Virtual Private Network) if you want to use services from outside the University of Paderborn that are only accessible within the university network. VPN ensures secure access to the university network from external networks (dial-in via other providers, external company or university networks). | ||

| + | As an alternative to downgrading the OpenSSL version, you can also unpack the certificate yourself. However, this can only be done via the terminal. If you have experience with it, this option is preferable. | ||

| + | If your cert file and key file have different names, you will need to rename them accordingly. | ||

Aktuelle Version vom 7. Juli 2024, 11:56 Uhr
Die deutsche Version finden Sie auf der Seite VPN unter macOS
Use Tunnelblick version 4.0.1 or newer. There is no longer any need to downgrade the OpenSSL version. Those who have set OpenSSL to version 1.1.1w as a temporary solution should create a new VPN connection for Tunnelblick with a new certificate and a new configuration file following these instructions. To do this, start at step Generate network certificate.
You need VPN (Virtual Private Network) if you want to use services from outside the University of Paderborn that are only accessible within the university network. VPN ensures secure access to the university network from external networks (dial-in via other providers, external company or university networks).

You have now downloaded your personal network certificates.
Set up Tunnelblick[Bearbeiten | Quelltext bearbeiten]
Download the configuration file, select the VPN you want to connect to and click Download. Normally, "Uni-VPN (Standard)" should be the right choice, but if you have problems with the connection, try "Uni-VPN-TCP" instead.
Note: You can click "Download" here and download your configuration file. This is not a screenshot ;-)
Direct all internet traffic through the tunnel?
- Accessing online resources may require that you route all network traffic through the tunnel.
- You do not need this option to simply access the network drives.
- Create a new folder - For example, name it "vpn-upb".
- This is what your VPN connection will be called later.
- Now put the personal network certificate and configuration file in this folder.
- Rename your personal network certificate to
Network_Certificate.p12 - Example: Change the file name
Network_Certificate_muster_078B30.p12toNetwork_Certificate.p12 - The configuration file should have an icon like the screenshot and end with
.ovpn.
My configuration file looks different! - What now? -Click here-
- When downloading, it can happen that the .ovpn file becomes a .txt file. However, we can change the file extension again relatively easily.
- Click on the configuration file. Now press cmd + i on the keyboard.
- "Name & Suffix" may now read .ovpn.txt.
- Delete the .txt.
- Then press the Enter key.

- Select "Only for this user".
- You will be prompted to enter your Mac password to install the configuration.
- Now click on the tunnel vision symbol in the menu bar at the top.
- Click connect on the desired VPN connection.
- In our example this is "connect vpn-upb"
- In the next step you will be asked to enter a password. Enter the import password mentioned above that belongs to the certificate.
- In addition, be sure to select the "Save to Keychain" option so that the password is saved (otherwise you will have to keep re-entering the import password).
- Wait until the font turns green and you are connected.
- You can quickly connect and disconnect the connection using the Tunnelblick symbol.

Common Issues[Bearbeiten | Quelltext bearbeiten]
Configuration file not readable[Bearbeiten | Quelltext bearbeiten]
When downloading, the .ovpn file may be turned into a .txt file.
Select the configuration file. Press the key combination cmd and i. If the file under Suffix ends in .txt, delete this part. The name should end with .ovpn.
Group VPN ports are blocked - TLS handshake failed after a timeout (60 sec)[Bearbeiten | Quelltext bearbeiten]
Group VPN connections are established over specific UDP ports. Normally these port sharings are problem-free because they do not overlap with other protocols. However, if your Internet access is of a restrictive nature and only allows certain ports, a connection problem may arise. This affects some university institutions or company networks. Home networks generally do not have this.
Solution:
- change your location or network
- Release the required port or talk to the IT department whether this is possible
- You can find the port used for your group network within the config file.
- If it is the hpc-pc2 network, contact the PC2 for alternative SSH access
