have you tried using a vpn, e.g. tailscale?

extremely easy to set up, if you are a selfhost purist, there’s headscale as a direct alternative.

only really good at doing stuff in a personal workspace, not really made for exposing to the public internet, still very possible tho

the system isn’t broken, it works exactly as intended. the system doesn’t need to be fixed, it needs to be replaced.

same sentiment as your statement, just brings the point across stronger
