Notes relating to network setup, topology and flows.
Multi-site Mesh
This has taken a few forms:
SoftEther
Worked for a long time, but there was always something..off about it. Never had any security issues but I always had my fears, and ultimately switched away from it despite how nice it actually was.
ZeroTier
Never worked.
Bare WireGuard
Worked alright but the setup was a bit janky (doubtless my own fault) and eventually switched it off
