Setup Reverse Proxy?

[TheDreadPirate]

Even if you use your domain, that domain will resolve to your IP. So if the goal is for these friends to not have your IP using a reverse proxy alone won't change that. Except if your friends don't know this fact.

If you truly want them to not know your home IP, you would need to rent a VPS and have that host your reverse proxy.

To answer your question, though, you would need to setup Caddy. Which we have docs for, linked below. There are other apps you could use like Nginx or Apache, but those are harder to configure. Caddy is simple to setup and can automate requesting certificates for easy HTTPS.

First you would need to update the DNS record for your domains to point to your public IP. Your domain registrar should have an interface in your control panel to set that up.
