IPsec is commonly employed by enterprise-grade VPN solutions such as FortiGate for its excellent security and richness of features, though open-source implementations such as OpenIKED and strongSwan also exist. It uses Internet Key Exchange (IKE) under the hood which is further divided into IKEv1 and IKEv2, the latter a more modern and secure version of the former.
Hi! Unfortunately, some ISPs in Turkey have recently started blocking Proton Mail: https://status.proton.me/incidents/dzl872r2tn5m. If you have an Android device, you can download our VPN from GitHub: https://github.com/ProtonVPN/android-app/releases. Log in with your Proton account, and connect to the VPN to access Proton Mail.
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.

I've been looking at this project for a while which may be interesting to you: https://github.com/Ysurac/openmptcprouter.
I recently bought a property where I cannot get a full fibre connection, but I can get 150-400 Mbps using 5G. I've been thinking about using dual 5G connections and tunneling my traffic via mptcp to a VPS to aggregate the connections.
