I'm looking to setup a site-site tunnel so I can remotely access stuff at mum's (she's in isolation because of this Covid 19 stuff) and using remote desktop control, connect her Mac to a video call.

For the Devuan infrastructure we do "virtual cabling" bmo "udptap" which is
available in experimental. It's similar to all else with, in my eyes, a couple
of advantages. The source project includes an openbsd branch which looks good
even if it's more or less untested.

However, for a one-off virtual cabling I would use "ssh -w"; as I remember that
works fine also on a mac (though I do remember there were some hurdles with
tun/tap).
