Wiresmith: Rust, auto-configs clients into a mesh

Maybe take a look at Wesher https://github.com/costela/wesher

I run a Wireguard mesh network with Wesher, and I am pretty sure that there are other projects to automate this. Is there a reason not to use them?

From a purely networking perspective, there are far better solutions than tailscale.

Have a look at full mesh VPNs like:

https://github.com/cjdelisle/cjdns

https://github.com/yggdrasil-network/yggdrasil-go

https://github.com/gsliepen/tinc

https://github.com/costela/wesher

These build actual mesh networks where every node is equal and can serve as a router for other nodes to resolve difficult network topologies (where some nodes might not be connected to the internet, but do have connections to other nodes with an internet connection).

Sending data through multiple routers is also possible. They also deal with nodes disappearing and change routes accordingly.

tailscale (and similar solutions like netbird) still use a bunch of "proxy servers" for that. You can set them up on intermediate nodes, but that have to be dealt with manually (and you get two kinds of nodes).

There are two factors at play here. The client's public IP actually depends on the gateway they use on accessing the internet. You can disable routing and your clients will keep their public IP and general internet access won't go through the VPS. However, if you want the traffic between "clients" also skip the VPS, then you want a mesh network. wesher and wg-meshconf can help you on configuring them.

Have you considered https://github.com/costela/wesher or does this not fit your use case?

I use Hashicorp Consul and Hashicorp Nomad for service discovery and task scheduling respectively, with wesher for my internal private management network that Consul, Nomad, etc run on to protect the management interfaces. Fabio bridges the gap between the wesher wireguard VPN and the rest of my home network.

How does your solution compare to wesher?

How does it compare to https://github.com/costela/wesher?

The best way to securely connect your functions to your other resources is with an encrypted mesh network like NetBird. NetBird lets you link your infrastructure together using a zero-config private WireGuard network that works across cloud, serverless, and on-premise infrastructure.

NetBird - NetBird is an open-source VPN management platform built on top of WireGuard® making it easy to create secure private networks for your organization or home.

NetBird simplifies Kubernetes access with its zero-configuration approach, leveraging WireGuard's simplicity and strength. It seamlessly integrates with various tools, offering transparency and high reliability as an open source solution.

NetBird is a configuration-free, peer-to-peer private network combined with a centralized access control system. Utilizing a WireGuard-based overlay network, it ensures encrypted connections between machines without the need for complex configurations such as port openings, intricate firewall rules, or VPN gateways. Prioritizes security with intuitive management of granular access policies for secure remote access, applicable universally across any infrastructure. petr205 explains, "Their SaaS version is free up to 100 machines and 5 users, but the self-hosted version is exactly the same and has very low requirements."

It is always great to see another solution using Wireguard, which is a great technology for modern private connectivity.

I built https://github.com/netbirdio/netbird, which can be self-hosted and offers an option to run Wireguard without managing firewalls for P2P connectivity.
