Plex Lifetime pass holder
Synopsis:
- I’m an IT professional with a broad amount of expertise and experience.
- My Plex server is installed on my Synology NAS.
- I have 2 broadband connections: VDSL with a single static IP (WAN1) & Starlink using DHCP for it’s external CGNAT’d / public facing IP (WAN2).
- I have approximately 150 users who frequently stream media from various libraries on my server.
Problem
Obviously (as I understand it) your on-prem’ Plex server can only utilise one broadband connection, as opposed to being load-balanced / distributed across 2.
I have port 32400 mapped manually with no particularly funky or exotic unorthodox configuration on my router.
Symptoms
Ever since commissioning my Starlink broadband and connecting it to my router as WAN2, My server’s Remote Access config bounces between showing as Available to my family of user one minute, then not available remotely the next.
As a result, my users (as I do as well) sometimes connect securely, but more often they end up connecting / streaming via the Plex relay service and thus are restricted to 2Mbit streams (I think 2 it the cap right?) when I could actually service up to 150MBps of aggregate streams with (for example) my Starlink connection.
My Hunch
I firmly believe that I need at least, to configure my router and perhaps my NAS’s network (routing) configuration to specifically point all of my Plex In-bound and Out-bound traffic to / through one of my 2 broadband connections (preferably Starlink), but to achieve this - I need to make my router aware of the Plex servers out there in the cloud (either IP’s or FQDN - either I’d be happy with).
I’m aware of the Worker IP Address’ which you can query if you pickup the link from the support pages (https://s3-eu-west-1.amazonaws.com/plex-sidekiq-servers-list/sidekiqIPs.txt), which I haven’t configured in my router or my NAS’s network config, but like I said - I think I need to setup strick router of all my Plex traffic from my NAS server to Plex’s server out there on the internet and vica-versa to assure only one broadband connection is utilised.
Once I’ve suss’t this issue out (and definitely not before), I might try to configure my router’s Load Balancing/Routing feature to use my Starlink connection for Plex unless the bandwidth drops below a certain speed (as is the case with peak-time traffic, something which Starlink make no secret of) - Which can be a massive drop in speed too!
For now I’m just desperate for the proper theory and solution from Plex (please nicely with a cherry on-top? 
) or any of you who’ve got a similar configuration or experienced the same type of issue yourselves.
Please nicely Plex-Gods and fellow Plexers … can anyone help me old with this long running issue i’ve been experiencing?
Thanks in advance
Ben S.
