wgsd VS ZeroTier

if your looking at setting up coredns aswell then i would highly suggest checking out wgsd https://github.com/jwhited/wgsd

https://github.com/jwhited/wgsd does NAT traversal with Wireguard, but you need to operate a CoreDNS server to do it.

More info on how it works: https://www.jordanwhited.com/posts/wireguard-endpoint-discov...

Another one which looks promising is wgsd, a dns like plugin to discover peer's endpoints that sit behind a NAT. For me this is part of the solution, however not a complete one, as my client devices are also on Android and Android TV.

that guide is literally someone promoting their CoreDNS plugin, so I'm confused as to what you mean: https://github.com/jwhited/wgsd

If they are behind a NAT that you can't do port-forwarding on then you may need to run some additional software like https://github.com/jwhited/wgsd so 10.10.0.2 and 10.10.0.3 know where to look for each other by asking 10.10.0.1

Our current implementation just has the nodes configured with PersistentKeepAlive by default, which works well enough for our small setup. In future iterations our plan is to incorporate another service. Our inclination is to use WGSD: https://github.com/jwhited/wgsd

ZeroTier - Layer 2 overlay network. They take decentralization seriously, and like to say "decentralize until it hurts, then centralize until it works." Written in C++.

EDIT - I'm tired and cross-eyed after a bunch of internet searching and rabbit holes... A supposed ZeroTier dev said on April 25, 2023 that this would be addressed in a future release of the app in this thread: https://github.com/zerotier/ZeroTierOne/issues/1952. On August 10th, another engineer said that they are waiting for a car to be delivered.

If you just want to connect between your devices, you don't need any hardware. Just install zerotier on them.
