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.
