Ok so lets say i have three proxmox hosts that are all directly exposed to the internet and have one public ip each.
What would be the best way to cluster them / create some kind overlay network that allows them to securely communicate with each other?
My first idea was to just create a pfsense vm on each node and then do a site to site vpn between each server, but that would not be scaleable (if each node has a tunnle to each other node) or reliable (if everything goes over a single node / main vpn server)
Also since i dont want to be reliant on one provider, i dont plan to use sth from the provider like vlans from hetzner and
yes i am aware that multi site clusters arent recommended, but since i am only interested in centralized management and offline migration (and all servers have a 1gb+ connection) i am not to worried about that
