HI Guys! A design question: I am using a VPS as a lighthouse for my homeserver and run vpncloud between the VPS and my NATed home server. I actually do pipe traffic 80/443 on VPS -> socat over VPN (vncloud) -> Homeserver. This has the beaty of SSL beeing terminated at my home and not in the VPS. Looking into Netmaker right now -> changing 443 to an another port would be awesome, so i still can capture incoming traffic on port 443 and fowarding it with socat. Running the WebUI on a different port is not a problem i guess, but the letsencrypt validation does need the port to be 443 right? what challenge method is used?
