Question

I read Wireguard white paper lately and later discovered tailscale. This Software defined Networking/VPN kind of domain was really interesting to me and upon exploring further, I came across following interesting projects:- tailscale (WireGuard)- innernet (Wireguard)- headscale (Wiregarud, control server for tailscale)- nebula- ZeroTier (virtual ethernet)- weron (WebRTC for SDN)What other interesting SDN/VPN projects are out there that you find very interesting/magical?(edit to fix formatting)

I like OpenZiti - https://openziti.github.io/. It can be embedded inside anything. They recently did it to Prometheus and are working on Ansible - https://openziti.github.io/articles/zitification/prometheus/.... Allows you to close all inbound ports so no external network attacks are possible.
