VPN stands for "Virtual Private Network". The VPN client is software that allows an encrypted, secure and authenticated connection from remote locations to the ETH network. Once the connection is established, you get an ETH Zurich IP address. Many ETH services do not recognize users with an Internet provider other than the ETH Zurich(e.g. Cablecom) as ETH members and therefore deny them access. With a VPN tunnel they are allocated an ETH internal address and are thus accepted by these services. The service is available to all ETH Zurich employees and students for free.
