Can there be a version without networking black magic?

Is your feature request related to a problem? Please describe.
I have a caddy server running on a raspi behind a cloudflare tunnel and want to reverse proxy through caddy where its much simpler than traefik. In my caddyfile I have the url I want reverse_proxied to https://localhost:5173. Here's the kicker, the proxy fails with a bad gateway on my laptop BUT if I type https://localhost:5173 it works, which it shouldn't. How is localhost on my laptop able to access the raspberry pi? IMO networking should be left up to the end user to best fit their needs

Describe the solution you'd like
Remove all the black magic networking. Just tell it what port to run on.

It looks like you can adjust the port using the PORT environment variable:

You also likely want to ensure PUBLIC_HTTPS_ONLY is false, and PUBLIC_ORIGIN is the URL that caddy is exposing, rather than anything internal.

This error is almost certainly occurring because Caddy doesn't trust the certificate that is being served by default - I've run into the same thing with Traefik when dealing with self-signed https internally
