In response to the discussion on a recent thread about whether to trust Cloudflare, as some people are not very comfortable with it terminates HTTPS (MITM).
There is this thing called Fast Reverse Proxy (FRP) https://github.com/fatedier/frp
It’s open source, very lightweight and I have used it in multiple instances. Frankly there doesn’t seem to be a lot of people know/use it here. The idea is you deploy this on a VPS with public IP, and have your server at home connect to it. It is pretty much like your own Cloudflare tunnel, only you have much more control over it (ports, TCP/UDP/HTTP, auth, etc).
I use it on the cheapest VPS ($5) I can find close to where I live. It acts as a simple TCP reverse proxy to my server, where Nginx Proxy Manager handles the actual HTTPS. (You can let FRP handle HTTPS but then you need to think about if you trust the VPS and also keep the certs updated there, so nah.)
It’s developed by a Chinese dude as it is pretty much a necessity for selfhosters (mostly minecraft servers) in China, since Public IP is scarce there and most people live behind CGNATs.
Personally, when I used to route my home services through a VPS- I used a simple VPN tunnel from my VPS to my home network, which my home router would establish (dynamic IP).
From there, my firewall dictated what was actually allowed to enter through the tunnel… and the reverse proxy, did its thing.
