Hi,


`nmcli device connected` can do one of two things:

1) if no suitable profile exists, create one and activate it.

2) if a suitable profile exits, activate it. In that case, it's very
much the same as `nmcli connection up $PROFILE`, except that
NetworkManager will automatically find the profile.


VPN profiles aren't handled like regular profiles, and hence `nmcli
device connect` wouldn't work for it anyway. That probably should be
improved.


Instead, create/modify the profile to your liking. Start by looking at
the available profiles with `nmcli connection`. Activate the right one
with `nmcli connection up`.





best,
Thomas
