On my home server I also host a VPN, which is based on the OpenVPN protocol, and which is secured by password-challenges and encryption keys. From time to time I carry out a test of this VPN – i.e. from outside my LAN – to make sure that software-updates and other changes have not caused it to stop working.
Today I went to a public WiFi hot-spot, and carried out such a test.
This test was a bit different from earlier tests, in that it was the first time I used my new Pixel C tablet as the client.
The test was a full success. At first, after I had logged in to my VPN, I tried pinging another computer on my LAN. Then, I created a remote desktop session on one of my computers, in which the desktop session was being handed through to my tablet, by way of the VPN.
What this means is that my new Android 7.1.2 tablet is fully compatible and set up to use this feature.

I have noticed that performing this test also knocked my Google Calendar app out from syncing. This caused a famous situation, in which the app was still displaying my schedule, but the tablet was no longer giving any notifications, for the reminders programmed in my calendar. This caused me no immediate distress, because I possess sundry other devices, which give alarms to signal the same reminders.
But the way in which I got the tablet to rejoin this chorus, was by first telling the Android Application Manager to erase the Cache of this one app, and then to go into the Accounts settings panel, to go into my Google Accounts, and from there, to toggle syncing of the Calendar Off and then On again.
After that, the app has been sounding all the reminders as before.
