DDNS with Caddy as a reverse proxy server

[TheDreadPirate]

I am not sure if DDNS addresses get resolved in that field. Hypothetically, if it did resolve DDNS addresses, I'm not sure it would dynamically update the filter without requiring a restart of Jellyfin.

Regarding the device access restrictions, from the setting's comment.

This only applies to devices that can be uniquely identified and will not prevent browser access. Filtering user device access will prevent them from using new devices until they've been approved here.

I'll experiment with it a bit later today and get back to you. I've never used the feature myself.
