VPN stands for Virtual Private Network und enables for a secure connection via insecure networks.

The VPN Service in Detail

Insecure networks - e.g. the Internet - in principle allow unauthorized tapping and falsification of communication relationships. To prevent this, VPNs use special protocols that encrypt the data. At Chemnitz University of Technology, the Transport Layer Security Protocol (TLS) and the IPsec standard (IP Security) are used for this purpose. In principle, a tunnel is established between your computer (at home or on the road) and the VPN server at Chemnitz University of Technology, through which any IP data is sent in encrypted form.

Whom is this service intended for?

  • Users, who want to access to the TU Chemnitz campus network securely way with their own computers via external internet providers
  • Users who want to access the campus network of Chemnitz University of Technology securely from a connection at another university or any other internet access (e.g. on business trips, congresses etc.)
  • Users who want to access the campus network of Chemnitz University of Technology securely from their computer via data outlets in public rooms of Chemnitz University of Technology.

When the connection is established, an authentication with your URZ user ID and password is performed. If a VPN tunnel is successfully established, the computer receives an IP address from the address range of Chemnitz University of Technology. This also allows access to services that require a sender address from the address range of the university.

Preconditions

  • a valid user login
  • a computer with a with functioning Internet/network connection or WLAN connection functioning in the WLAN radio network

A so-called VPN client must be installed on your computer. If no VPN client can/may be installed on your computer, a purely browser-based access to web-based services of Chemnitz University of Technology is possible via web browser (WebVPN).

The TLS-based Anyconnect client from Cisco is recommended. Campus licenses are available free of charge to all students and employees of the university.

Under Linux, the freely available IPsec-based VPN client VPNC or thefreely available TLS-based VPN client Openconnect can be used.

Mac OS version 10.6 and higher has its own native IPsec-based VPN client on board. The included native IPsec-based VPN client can also be used on iOS devices (iPhone, iPad, iPod touch) and Android devices.
