Option to manually specify the announced IP address for the server?

Plex always listens on the machine’s natural LAN address. That will automatically be registered as the first entry, and doesn’t need to be manually entered.

If additional entries are needed, I don’t think the order of the Custom server access URLs matters or is preserved.

I’m pretty sure that this is the order:

  1. Local LAN IP : 32400
  2. All Custom server access URLs entries, ordered randomly
  3. Detected Public Internet address, if Remote Access is enabled
