I've been playing around with self hosting for file sharing, backups, and a handful of other ideas I might one day get round to. I like the idea of a mesh VPN and being able to, for example, connect a travelling laptop to a 'host' laptop nearby, though my only public ip is a VPS in another country.
Of all the options I found, I liked the look of Nebula most. Fiddly in some places, but it's working nicely for me, and I appreciate some of the simplicity of design.
I'm wondering if people here have much experience of it, though? My biggest concern is over its future. With,
The Defined Networking site focusing on making money off it, and
The Android app doesn't allow full configuration (including the firewall, so I can't host a website from a phone) but - I heard - does if you use Defined Networking's paid service for configuration,
makes me worry they might be essentially trying to deprecate viable FOSS Nebula in favour of a paid or controlled service.
Can Wireguard to NAT traversal? Let's say I have a publicly facing server A and then two devices B and C behind two separate nats. Can B reach C directly via hole punching by A?
I don't know a lot about Tinc, but it looked to me like both Nebula (directly inspired by Tinc) and Tailscale solve problems Tinc has, and improve on its excellent but older design.
