If you cannot connect to OpenVPN and receive the error message "UNKNOWN/UNSUPPORTED OPTIONS": You can only use the OpenVPN app from version 3.4 if you have installed the current configuration file. You can find instructions on how to do this in the Import configuration file section. You do not need to install a new user certificate.
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.

- Open this .OVPN12 file on the iOS device, select "Open with OpenVPN-Connect" and import the certificate there.
