    I havent been able to try it out but nebula i think made by the slack Team seems to be another Option.

    I believe this is is very similar to the intended use case of Nebula. Might be easier if you're interested in a bare-bones and totally self-hosted option.

    Nebula implemented Relay support (1) last year although it is marked experimental.

    Nebula, Nebula seems like a great option, using a faster than wireguard protocol, and it supports most of the clients that I would need. But it seems slightly more complicated to set up and it is geared more towards commercial use cases. I also don't know the state of DNS in it (and how experimental it seems), I have PiHole running on the server and would like to be able to use it outside the network.

    nebula[0] may be interesting; you can allow list connectivity for specific groups, all burned into the cert used to join the network. It uses some NAT hole punching orchestration to accomplish connectivity between hosts without opening ports.

    The main painful thing I've found has been cert management. PKI, as usual, is not a solved problem.

    I've managed to do some fun stuff using salt + nebula on the hobby side.

    >I've been meaning to look into this with wireguard, but I'm having trouble searching for/finding how to do this. Is "bastion host" what I'd want? Also is there a way to ensure the VPS cannot access the network as well, and just tunnels it essentially?

    First, yes a search phrase like that should get you the right terms, though there isn't anything inherently special about it. If multiple systems are connected to one system with wireguard giving them all access to a given subnet is straight forward. As far as the VPS, it can indeed access that subnet too, since it's acting as part of the subnet, but you can use normal firewall rules on the far side internally to control what can talk to what and how. And in this kind of specific instance the WG is more about controller public facing surface area, the Bitwarden/Vaultwarden traffic in flight is itself encrypted.

    Second though, having said all that I think if you worried about the VPS bit (or even if not) you should take a look at the Nebula SDN [0, 1] instead. It's built on the Noise encryption framework as well. There, the fixed IP node (the "Lighthouse") primarily acts to let other nodes know their mutual addresses, and they then attempt to form a direct link with no bouncing through a bastion, it's a real mesh. This generally works even if both are NAT'd, and if not it's transparent fallback and still encrypted between them. Depending on distance between nodes this can be a lot lower latency as well. With Nebula you establish an internal CA (super easy built-in tool for it) and that doesn't (and absolutely shouldn't) live on the lighthouse.

    I'm fortunate enough to have fixed IPs available to me at home and office and have tended to use WG a lot just because it's had more advanced support and performance in constrained environments for me (kernel support in Linux and now BSDs). Nebula has been super slick though and I've been using it more and more. It makes all this really easy.
