For the VPN authentication, you need to use the same password and login method as with Wi-Fi:


Realm Login name
for studentsusername@student-net.ethz.ch
for employees and longterm guestsusername@staff-net.ethz.ch
if you are using a group realmusername@"realm".ethz.ch

If you are not sure to which realm you belong, you can check it here https://realms.ethz.ch


VPN provides a way to access the ETH campus network from outside the ETH. This is a requirement to access several IT services from outside ETH locations (i.e. when you are connected to the network of an external university, a hotel WiFi network or telecommunication provider network). The technique behind that is called VPN and stands for Virtual Private Network.

Please note, after you have established a VPN tunnel all network traffic (also access to non-ETH sites) from and towards your laptop will be looped trough the ETH network.

Follow these steps to access the VPN tunnel.
