It does not say that in the documentation. What the documentation does have, however, are extensive instructions on how to make Jellyfin accessible on WAN: https://jellyfin.org/docs/general/post-install/networking/ https://jellyfin.org/docs/general/post-install/networking/reverse-proxy/


For some reason they recommend against directly forwarding Jellyfin’s ports, but reverse proxies are fine. I expect this is because the default configuration doesn’t use SSL.
I think you’ll find without exposing ports to the open internet we would not be having this conversation right now. Which, I suppose, wouldn’t be such a bad thing.
