Problem adding new port mapping on Docker

[Slinkynose]

I have the Linuxserver Plex docker running on the Custom:proxynet network type based on the SpaceInvaderOne tutorial.

 

I am trying to add another port (33400 for Webtools), but it doesn't seem to save when I apply the settings and restart the container. It doesn't show up in the port mappings list.

 

Any ideas?

If it's still being assigned an IP separate for the container, then any and all port mappings are irrelevant anyways, as the container will use whatever it needs

Thank you Squid.  I've seen this reply on many threads with port questions. I thought it only applied when in host mode. The Plex docker does have its own IP on the proxynet subnet. 172.18.0.4.

 

 

As a general question though, why am I not able to add a new port mapping to a container? The config page let's me create and apply, but it doesn't actually apply?

 

Maybe I am barking up the wrong tree for why Webtools is inaccessible, and I will post in the Plex container forum.
