VPN on iOS

ZIM HilfeWiki - das Wiki
Die deutsche Version finden Sie auf der Seite VPN unter iOS

These instructions show you how to set up a VPN connection to the university network on the iPhone and iPad.
A Virtual Private Network ensures secure access to the university network from external networks.
Certain services are only available from the university network. This includes, for example, accessing network drives and downloading online resources from the university library homepage.
Do you want to access these services and are not at university? Then you need a VPN connection.

What needs to be done?[Bearbeiten | Quelltext bearbeiten]

  • Install OpenVPN Connect from the AppStore.
  • Download a Personal Certificate File whose file extension is .OVPN12.
  • Open this .OVPN12 file on the iOS device, select "Open with OpenVPN-Connect" and import the certificate there.
  • Download the configuration file:

  • Use this to set up the VPN connection in OpenVPN.

Step-by-step instructions[Bearbeiten | Quelltext bearbeiten]

Install OpenVPN Connect[Bearbeiten | Quelltext bearbeiten]

Vpn-ios-1.png Install the OpenVPN Connect app. You can find these like other apps in the AppStore.

Then open the OpenVPN Connect app and agree to the terms of use with "Accept".

Import network certificate[Bearbeiten | Quelltext bearbeiten]

For the VPN connection we need a network certificate. You cannot use the Eduroam certificate that may already be installed.

  • Open the service portal using Safari.
  • Log in with your university account.


Note: Do not use an alternative browser such as Google Chrome or Firefox for this. Downloading files in other browsers is not permitted on iOS.

  • Now the OpenVPN app opens.
  • Click "ADD" to import the certificate into OpenVPN.
  • Enter the password for the certificate. We have just copied this to the clipboard.


Import configuration file[Bearbeiten | Quelltext bearbeiten]

Now we need a configuration file. To do this, we switch back to the Safari browser.
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 on "Download" here and download your configuration file. This is not a screenshot ;-)

  • 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.

Note: When the VPN is active, all of your internet traffic is redirected via the University of Paderborn servers. So only activate the VPN connection if you actually need it.

Check VPN[Bearbeiten | Quelltext bearbeiten]

You can check the functionality of the VPN by calling:
