Question about UPnP and Plex Docker for unRaid

[Polopollo]

Hello, super dumb question (I'm still learning all the terminology)

 

I noticed that when I want to access my Plex server on my phone outside of my home, it displays a message that the server is not directly accessible. But I still can access it somehow.

 

Now I want to do things right. I have a basic router for now, and I binded my unRaid to 192.168.0.104.

I activated UPnP to do all the port forwarding automatically, here are some images:

Now the fact that it doesn't work, does that mean I need to set a manual port forwarding for TCP (and UDP?) for the port 32400 to 192.168.0.104 ?

 

Ideally I would love to just have UPnP and not have to forward all my other docker ports to my unRaid machine. Is there a way to do so? If yes what am I doing wrong?
