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?
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.
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.
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.

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 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.
