Reverse proxy configuration
I am currently using NPM as my reverse proxy. It runs on a Raspberry Pi which also does pihole. I have a separate server for other non internet critical systems.
So local IP address mappings point a subdomain to the pi's IP, then nginx points to the correct device and port.
I am wondering if Traefik works the same way. Can I run Traefik on the Pi, then point my other sever at it? (I believe Caddy doesn't allow this)
Caddy supports it too: https://caddyserver.com/docs/caddyfile/directives/reverse_proxy
I just replaced NPM with Caddy this week. It's straightforward once I understood the config file. Why the switch? NPM is too heavy for my needs and I need to do extra manual works to update the SSL certs.
Looks like you should be able to do so:
