VPN (Virtual Private Network) is needed if you want to use your computer from home to access services that are only accessible within the university network. VPN guarantees secure access to the university network from other networks (dial-up via other providers, external company or university networks). VPN makes it possible to transfer data over an encrypted connection (tap-proof tunnel). This connection is established between a VPN server at the university and a VPN client on your computer on the Internet. By connecting to the VPN server, your computer becomes part of the university network.
You need VPN if you
- use the green cans within the university (for security reasons you can only access the rest of the network via a VPN connection)
- want to access licensed electronic information media of the University Library
- use a license server of the university,
- want to access protected pages of the university,
- would like to work with the TYPO3 CMS from home.
You do not need VPN if you
- want to read your e-mails on webmail,
- want to send e-mails via the mail server of the IMT.
To do this, either use the webmailer https://webmail.uni-paderborn.de or enter user ID and password with encryption in your e-mail program. You can find further information on the subject of mail on our portal page.
As VPN software, the IMT offers you OpenVPN. The VPN client from Cisco is no longer supported.
To use OpenVPN, you must install a network certificate. If you use the WLAN "eduroam", the certificate is already installed on your computer.
You can use OpenVPN under Linux, macOS and Windows. The use of OpenVPN on Android is free of support and at your own risk.
