Decentralized VPN with hole punching?(Tailscale with decentralized control server) (realbitcoin.cash)

Hey. I'm currently using Tailscale with a self hosted control server(headscale). The problem's that when the control server goes down for several days(Internet outage, here, in Iran), the clients get lost. And I have to come up with a new control server.

So I'm looking for a solution similar to Tailscale+Headscale, but with decentralized control server and relay.

Note that raw wireguard is not a solution. As some clients are(or might be) behind NATs. And then they will either need hole punching or a relay.

What's your threat model? No matter what, hole-punching will require some sort of relay. Yggdrasil's likelier than Iroh to have available community servers if you need a hole punched in an adversarial context.
