ZeroTier One for the VPN
I have to shout out to ZeroTier one - I think I first saw it mentioned on the Reg a few years back. Fast forward to today and I run it on every device I have, on multiple OSs, and then promptly forget about it. I don't notice it when I move between home and office - everything works, including multicast traffic.
It just works and I don't have to think about it is pretty much the highest praise I can offer.
