Howto establish a VPN (Virtual Private Network) connection to the ETH campus network from a Windows computer

This quick guide shows you how to connect to the ETH campus network using VPN (Virtual Private Network) from a Windows computer. This is needful if you want to connect ETH network services from computers that are not located on the ETH campus.

Situations when you need to establish a VPN Tunnel prior the network access

  • This can be your personal laptop connected to your internet connection at home.
  • You are staying in a hotel and need to access a service within the ETH network by connecting your laptop to the WIFI network of the hotel.
  • For some services it can also be necessary to connect with VPN, when you are connected to a guest network somewhere else at ETH other than your institute.
  • The decision, when and if you need to establish a VPN tunnel should also be found within the documentation of the specific network service. If you are unsure ask your local IT specialist.

rule of thumb: If you need to connect a network service or resources from a machine different from your usual office computer or when you are connected to the internet by a cable or WIFI at another institute, university or at home ☛ establish a VPN tunnel
