N2N Edge GUI VS Tinc VPN

Not sure if n2n would work for your setup. Apparently, there's a gui now. I haven't tried it on windows. Source: about 2 years ago

No love for tinc[1]? It's the granddaddy of mesh networking, long before Wireguard, and while it's not quite zeroconf, it's very simple to setup and maintain. It also runs on everything. [1]: https://tinc-vpn.org/. - Source: Hacker News / 6 months ago

Two other options are Tinc https://tinc-vpn.org/ or Nebula https://www.defined.net/nebula/. Source: over 1 year ago

And there is Tinc; the OG overlay network. I don't have experience with this. Seemed a bit of a pain to setup. https://tinc-vpn.org. Source: almost 2 years ago

For what its worth I have used the open source Tinc VPN [1] for mesh multihop routing for ages. It is nowhere near as fast as Wireguard but I could envision Tinc incorporating support for Wireguard if the author were so inclined. Like you mentioned Tinc does not mesh with other VPN's AFAIK.

This is actually very simple in concept and is just as simple or even simpler to do with tinc (https://tinc-vpn.org). Since I can use tinc in bridge mode, I can run tinc on the upstream server and on a local machine which then provides access to several physical machines without running extra software on each of those machines, which is particularly useful for machines that are resource limited, like my Macintosh... - Source: Hacker News / about 2 years ago
