tinc VS Netmaker

But both Nebula and tinc max out at around 1 Gbit/s on my Hetzner servers, thus not using most of my 10 Gbit/s connectivity. This is because they cap out at 100% of 1 CPU. The Nebula issue about that was closed due to "inactivity" [2].

I also observed that when Nebula operates at 100% CPU usage, you get lots of package loss. This causes software that expects reasonable timings on ~0.2ms links to fail (e.g. consensus software like Consul, or Ceph). This in turn led to flakiness / intermittent outages.

I had to resolve to move the big data pushing softwares like Ceph outside of the VPN to get 10 Gbit/s speed for those, and to avoid downtimes due to the packet loss.

Such software like Ceph has its own encryption, but I don't trust it, and that mistrust was recently proven right again [3].

So I'm currently looking to move the Ceph into WireGuard.

Summary: For small-data use, tinc and Nebula are fine, but if you start to push real data, they break.

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

Have a look at full mesh VPNs like:

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).

Two other options are Tinc https://tinc-vpn.org/ or Nebula https://www.defined.net/nebula/

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

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 LC II and LC III+:

It'd be nice if it weren't so difficult to get public addresses.

I clicked expected some broken analogy between https://tinc-vpn.org/ and the Catan board game, but instead it is a Catan implementation. Fair enough.

will generate a real-time network graph using the Graphviz DOT language. It's a cool feature that I find quite useful.

My plan is to set up an EC2 instance and host a VPN, considering options like Netmaker, OpenVPN, or Tailscale. The goal is to connect these devices to the VPN, enabling SSH access from any connected node. This method seems cost-effective(Considering I want to use 100s of devices and potentially 1000s) and straightforward, requiring a simple setup with a sudo apt command on the Raspberry Pi.

I'm wondering if there are any alternative approaches to achieve this. Is something like Netmaker or Tailscale feasible enough? If you have any suggestions, I'd greatly appreciate it.

Honorable mention:

SuperHighway84 - more of a Usenet-inspired darknet, but I love the concept + the author's personal website:

Exciting news to share! Netmaker has officially embraced open source. This momentous decision was unveiled at the Open Source Summit in Europe when the pull request successfully merged, transitioning their server from the SSPL to the widely recognized Apache License 2.0.

While we've encountered some challenges and worked with vendors like Cisco to find solutions, I'm curious about recommendations for SD-WAN providers that are well-suited for SASE users. This includes not only Zscaler but also other options like Netmaker, Palo Alto, Cloudflare, Cisco, and Forcepoint.

Now, my main question is how I can link my DDNS host endpoint with my EC2 instances, allowing only my home network to access them. I've come across a variety of suggestions, such as Netmaker, OpenVPN, Tailscale etc. but I'm curious to hear your opinions on these solutions.

HN is somehow always timely. Currently, these folks expect me to sign a CLA for a one-byte change to their README: https://github.com/gravitl/netmaker/pull/2516
