I’m happily serving a few websites and services publicly. Now I would like to host my Navidrome server, but keep the contents private on the web to stay out of trouble. I’m afraid that when I install a reverse proxy, it’ll take my other stuff online offline and causes me various headaches that I’m not really in the headspace for at the moment. Is there a safe way to go about doing this selectively?
That’s the standard behavior. Read the documentation for whatever reverse proxy you want to use.
The standard is that everything gets captured by the proxy? I want to leave the HTTP and Gemini servers public. I also want those and SMB to remain accessible on the LAN.
No, the standard is that it routes only what you configure.
Wonderful. Thank you!
I just don’t put the ports on the proxy config.
So those ports that I don’t put in the config remain publicly accessible? That would be perfect.
The ports you don’t put in are not publicly routed.
I use NPM and only have 3 services routed outside my network.
A reverse proxy is basically a landing place that acts as a middle man between the client and the server. Most people set it up so that all traffic on 80 or 443 go to the reverse proxy, and then the reverse proxy gets the correct website based on the host header of the request.
If you are currently serving multiple websites on your server, then that means you are serving each website on a different port.
So, just make sure that the reverse proxy is serving on a port that is not used by your other sites. It will only respond on it’s own port, and it will only serve the site(s) that you have configured in the proxy.
You’ll be fine!
Thanks, that’s a great explanation. I’m looking forward to being able to SSH in without port forwarding.
I agree that you would want a VPN for that. Look into something like tailscale.
I would use a VPN to ssh

If you don’t configure your other services in the reverse proxy then you have nothing to worry about. I don’t know of any proxy that auto discovers services and routes to them by default. (Traefik does something like this with Docker services, but they need Docker labels and to be on the same Docker network as Traefik, and you’re the one configuring both of those things.)
Are you running this on your local network? If so, then unless you forward a port to your server on the port your reverse proxy is serving from, it’ll only be accessible from the local network. This means you can either keep it that way (and VPN in to access it) or test it by connecting directly to your server on that port and confirm that it’s working as expected before forwarding the port.
Thank you so much. That clears up all my doubts. I’m running an ARM server ok the lan with port forwarding for HTTP (80) Gemini (1965) and SMB (not forwarded).
I made a typo in my original question: I was afraid of taking the services offline, not online.

Gotcha, that makes more sense.
If you try to run the reverse proxy on the same server and port that an existing service is using (e.g., port 80), then you’ll run into issues. You could also run into conflicts with the ports the services themselves use. Likewise if you use the same outbound port from your router. But IME those issues will mostly stop the new services from starting - you’d have to stop the services or restart your machine for the new service to have a chance to grab the ports while they were unused. Otherwise I can’t think of any issues.
That’s reassuring. Thanks, I was struggling with the concept and where to start but I should be fine now since I’m handy enough with a terminal.
A typical use case is to forward a single port to the proxy, then set the proxy to map different subdomains to different machines/ports on your internal network. Anything not explicitly mapped by the reverse proxy isn’t visible externally.
First of all, doesn’t Navidrome have authentication? So, I don’t see why exposing it to the public is a problem.
Second, some reverse proxies support basic auth. This way, you can password-protect some services and is useful if the service does not have its own authentication. Here as an example snippet for Caddy:
example.com { basic_auth { # Username "Bob", password "hiccup" Bob $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG } reverse_proxy myservice:8000 }You’ll have to look up the docs for other reverse proxies.
Thanks. You’re right about Navidrome supporting authentication. I’m using HTTP instead of HTTPS, though. I was advised to use a reverse proxy to avoid potential legal issues.
What’s your reason for using HTTP? That seems like a really bad idea this day in age, ESPECIALLY if that’s something you’re going to make available on the internet.
They’re lightweight sites that exist to be accessed by vintage computers which aren’t powerful enough to run SSL.
Gotcha… as long as you understand that any device that receives that traffic can see exactly what’s in it! (no sarcasm intended at all… if you’re informed of the risk and OK with it, then all is well!)
