what's the simple way to map services to subdomains instead of specifying the port number? (lemmy.dbzer0.com)

I have a bunch of services running on my LAN, mostly from a single Debian machine. I access them at URLs like http://devicename.lan:portnumber. I would like to change to http://servicename.devicename.lan.

How it works now: The router (openwrt) sets a static IP per device and the port number is selected by the application or system unit running it.

What is the absolute simplest way to accomplish this? I don't mind if it is managed by the router or by the server machine itself. Hoping for something that can be configured with a text file or web interface or other basic mathod.

These sevices are private, just for me and I have no plans to ever access them externally. I have so far avoided any certificates or SSL or other stuff. I don't use docker and would rather not get into it right now. I like my domain name setup how it is with fake local domains.

Hoping this could be possible without making a whole project out of it.

If all your services support binding to a unix socket, I'd bind them to /run/<servicename>.sock or similar, and set up a reverse proxy that hits /run/$servicename.sock when serving $servicename.devicename.lan. If the service can't bind to a unix socket, you can probably socat it or similar, and keep using the generic reverse proxy. Then, all your router has to do is route port 80 to your Debian machine.

Check their docs, mostly.
