This documentation is written for english Android 7.0 and this functionality may look different in other Android versions.
1: Go to settings, choose “VPN” under “Wireless & networks”.
2: Set NMBU as name, L2T/IPSec PSK as type and vpn.nmbu.no as Server address. On the “Pre-Shared Key for IPSec” you must log in to Brukerdata and press the button called Personal. There you will find something called “Your VPN Key for L2TP Link” and that is the one you should use. (See below for detailed description for how to find this).
FIND the Pre-Shared Key for IPSec:
Go to: brukerdata.nmbu.no and log in with your username and password (same as Canvas, etc.)
NB! If you log in with a one-time password on Brukerdata then no information will appear under “personal”, therefore it is important that you log in with your username and password on Brukerdata.
Find “Your VPN Key for L2TP Link” at the bottom:
4: Open VPN connection by clicking on NMBU. Log in with email@example.com and NMBU password.
