XMR Externally accessed

Setting Up XMR internally everything works. By which I mean on the same network I point the xmr to the local ip address and port. When I set it to the domain or even just using the ip to access XMR externally Nothing happens there are no errors or logs I can find that say anything failed, to test im trying to turn the tv off.

Under settings I have the external IP and port

Under the display settings I have the external IP and Port

Im not sure if thats correct.

Any help would be much appreciated
