VPN Access

The Institute of Computer Science allows you to connect to the intranet from anywhere via VPN. (In simple cases, consider using an ssh tunnel.)

If you intend to connect to the VPN services provided by us, please make sure that you are running only recent software and operating systems that are receiving security patches. You are not allowed to connect to our VPN without making sure that you have the most recent security updates applied to your device, so please keep your systems safe!

General Information about OpenVPN

“OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.” (Wikipedia)

To authenticate, you will need to use your CS username and password. For further information on how to configure the various OpenVPN clients, please refer to the following instructions:
