A reverse proxy will achieve what you’re looking for, yes. I do precisely what you’re describing. I use “local DNS” on my pihole, with CNAMEs for each service pointing to my server IP address. I’m running Caddy on the server, specifically this (because my services are running in Docker containers): https://github.com/lucaslorentz/caddy-docker-proxy

As far as a “dashboard” app, you have options there as well. I’m using Heimdall currently, but Homarr also looks pretty nice.

Tangentially related: I’ve had this exact problem with quite a few games. Most recently, Subnautica: Below Zero. I often pause a game, go take care of a chore or something, then come back to having no controller input. Only recourse seems to be to exit the game and start it back up again. Using an 8bitdo Ultimate (non bluetooth) controller at the moment, Steam Deck connected to the official dock.

Anyone else have this issue? Any remedies you’re aware of?
