There’s no need to do all that. A reverse proxy could be hosted on your own house, it’s just a simple “control point” in front of all your equipment. It even could be a VM or container in front of your infra. But a simpler approach it’s to simply set up a vpn like zerotier/wireguard/cloudflared, and give access to your friends to just access the private IP you want. Don’t get me wrong, it is a great thing to learn about reverse proxies (I’d start learning how to do it using nginx if you ask), but sometimes you need to have a proper reason and not overengineering stuff.

Damn, just finished setting up CasaOS. That looks neat. Gonna try it.

I’m using it right now with Armbian on a Rock Pi 4C with a 128GB NvME drive. Planning to move the external 8TB hdd from the main lab PC to this, and run all low power tasks 24x7, and fire up the main rig when needed using WoL. I liked the UI, and the simple install process. But now someone mentioned it, I’d like to try Cosmos.
