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 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?
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.
My method:
VPS with reverse proxy to my public facing services. This holds SSL certs, and communicates with home network through WireGuard link configured on my router.
Local computer with reverse proxy for all services. This also has SSL certs, and handles the same services as the VPS, so I can have local/LAN speeds. Additionally, it serves as a reverse proxy for all my private services, such as my router/switches/access point config pages, Jellyfin, etc.
No complaints, it mostly just works. I also have my router override DNS entries for my FQDN to resolve locally, so I use the same URL for accessing public services on my LAN.
Thanks! Is the point of reverse-proxying your public-facing services to make them private?
It’s mostly so that I can have SSL handled by nginx (and not per-service), and also for ease of hosting multiple services accessible via subdomains. So every service is its own subdomain.
Additionally, my internal network (as in, my physical LAN) does not have any port forwarding enabled — everything is over WireGuard to my VPS.

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.
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 have authentication at the proxy level and is useful of the service does not support it. 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 shout Navidrome supporting authentication. I’m using HTTP instead of HTTPS, though. I was advised to use a reverse proxy to avoid potential legal issues.
How will a reverse proxy help?
Things that a reverse proxy is often used for:
Do any of these match what you’re trying to accomplish? What do you hope to gain by adding a reverse proxy (or maybe some other software better suited to your need)?
How are you currently serving publicly?
Linux running HTTP and Gemini servers. This is fine from home using port forwarding and afraid.org’s dynamic DNS.

That’s the standard behavior. Read the documentation for whatever reverse proxy you want to use.
FarraigePlaisteach@lemmy.world 1 month ago
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.
