Instructions for using VPN

Please make sure that you install all three certificates in order to avoid possible mistakes, when visiting the sites. If you installed the certificates in order to use eduroam, a second installation will not be necessary. 

The validation of these certificates will make sure that you're using the right connection and no imposter vpn is trying to steal your password/login information (phishing).

certificates for wireless / vpn (click to install):

• Deutsche Telekom Wurzelzertifikat CA 2
• DFN-CA Global-G2-Zertifikat
• DFN-PCA-Zerfitikat

If you click on the root-certificate and  the Uni Kassel CA certificate there will be a message saying that the certificate is already installed. This information is FALSE. Please click right on the certificate to download.

You need all three certificates to use the vpn client. On some operation systems the "Deutsche Telekom Wurzelzertifikat CA 2" (german telecom root-certificate) is already installed.

If you are using the Cisco Secure VPN Client under Windows, an existing VPN connection may cause problems when accessing websites outside the university network, making them inaccessible.
You can solve this problem by deactivating the IPv6 internet protocol.
