I am running a Proxmox node with a VM running a couple of Podman rootless containers, one of which is Jellyfin. I have also installed Traefik on a separate LXC unprivileged container. I have installed Tailscale on both the VM and the LXC.

What I want now is to create a reverse proxy so that I create subdomains pointing to my registered domain name, e.g. example.com.

I want when trying to access ‘jellyfin.example.com‘ the reverse proxy to point to the Tailscale IP or URL, for example ‘https://media.tbXXX.ts.net:8096‘. But that should work only when connected to the Tailscale network.

Is this even possible? If it is, can you point me to some resources explaining the whole configuration?
