Reverse proxy

Hello again.

well i have a server synology. I am using it as a plex server and it uses a reverse proxy so I do not have to open multiple ports on my router. I'm having trouble or I do not know if it's compatible for me to use a single port to connect from the outside on the virtualhere server.

My setup is like this.
