What is VPN?

VPN (Virtual Private Network) is a secure connection between private networks over a public network like the Internet. In order to keep data confidential, the traffic and thus the information on the public subnet is encrypted.

The traffic is directed through the tunnel to the TUNET. There the data is unpacked, decrypted and sent to target computers at the TU or the internet.

The user's encrypted connection ends at a so-called VPN concentrator.
