What network ports do I need to allow through my firewall?

The most important port to make sure your firewall allows is the main TCP port the Plex Media Server uses for communication:

  • TCP: 32400 (for access to the Plex Media Server) [required]

The following ports are also used for different services:

  • UDP: 1900 (for access to the Plex DLNA Server)
  • TCP: 3005 (for controlling Plex Home Theater via Plex Companion)
  • UDP: 5353 (for older Bonjour/Avahi network discovery)
  • TCP: 8324 (for controlling Plex for Roku via Plex Companion)
  • UDP: 32410, 32412, 32413, 32414 (for current GDM network discovery)
  • TCP: 32469 (for access to the Plex DLNA Server)

Note: This article is discussing ports in the local firewall of the computer running Plex Media Server. This is not discussing ports on a router.
