To use the VPN service at KIT you have to follow the installation instrructions for your operating system in the menu on the left.


Current Information about Split VPN tunneling

As VPN is heavily used at the moment you should consider using the Split Tunneling Configuration. But only if you are in a secure environment, for example if you work from home.

Please download the Split configuration from Custom configurations
Configuration #2 Split IPv4-Connect (l3, udp). Choose appropriate operating system and Port 1194.

Advantage: Only the traffic with destination KIT is going through the tunnel. So with split VPN your connection to the internet is more performant and you reduce load of the KIT VPN infrastructure.

Disadvantage: You won't be able to reach publishers directly which do not support user authentication because you won't be recognized as KIT user.

You need the default configuration file kit.ovpn. You can find it on top of the page with the installation instructions.

Custom configuration files

Normally, you only need the default configuration file. But for special requirements there are further VPN tunnels. For these you need custom configuration files that you find on Custom configuration.

Split-Tunneling

With split tunneling only the traffic with destination KIT goes through the VPN tunnel.

In case of using split tunneling with network manager in Linux make sure that Use this connection only for resources on its network" is checked in the NetworkManager under IPv4 settings →routes.

 

Establish a VPN connection from multiple computers simultaniously

To establish multiple connections to the OpenVPN server simultaniously you have to add a unique identifier to the user name to distinguish the clients. The identifier (e.g. the computer name) has to be added after the original user name, seperated by a /, and before any @.

Example: You can simultaniously log in with user/computer1 or user/computer1@vpn-split and user/computer2@vpn-split. You can choose any identifier.
