I am considering buying a PlexPass, but I am far from comfortable to open a public Internet port (32400) to my PMS. Is there a way to advance the Plex architecture to avoid the need to have public Internet port open? It is quite a security risk.
Currently the myPlex seems to be hosted at Amazon AWS so opening the port got "only" 18.104.22.168/14 helps a bit.
