Remote connection - Can see things but nothing plays!

[mherring]

This is odd. Remotely i can login and see everything navigate and change settings but i cant seem to get anything to play!

Running on an asustor NAS with jellyfin running in docker
However if im on my Local Network it works fine!
Any ideas what could be the cause?
I have ATT and have things port forwarded as follows (Yes i know these are not ideal, im just racking my brain trying to sort out this issue)
asustor nasTCP/UDP: 8000-9000 DdnsTCP/UDP: 10000-20000 asustor web serviceTCP/UDP: 5000-6000
