Is NAT loopback/hairpinning required for Sonos to work with Plex?

Is NAT loopback/hairpinning required for Sonos to work with Plex? I have Eero, which doesn't support NAT loopback / hairpinning. I have read lots on these boards but haven't found a definitive answer. If it is not required, is there a work-around? Thank you.

    It is required. Not sure if there's a work around (unless you consider Plex Cloud).

    Some routers may internally support this but not provide a setting for it...

    Also, some folks have found that manually creating the port forward, rather than letting it be automatically created through UPnP, will work in the absence of a NAT loopback/hairpin option. It really depends on your router.

    OK, So are we creating the Loopback for each Sonos device?

    If your router requires that you create a loopback manually, then yes you would want one for each Sonos device (or any Sonos device that you would be using to play music from Plex). My router (pfSense) just has a "NAT Reflection" option that I enable on the port forward, and that seems to allow it to work when any internal device makes a request to that port on the WAN address.

    This is all new to me but it sounds like I may be having similar issues. I'm using Luma for my routers, Sonos can find Plex and see all my library on my Synology NAS, but when I try to play a file it tells me it's unable to connect to Plex. Luma allows me to set up port forwards - I tried setting up port forwards on Luma using 32400 (for Plex) on each Sonos device, but that isn't working. Am I totally mixing everything up?

    I am too a bit confused on how to get the NAT hairpin/loopback setup on my TP-Link Archer D7. I have remote access working on my plex server/router, but when i go to create a port forward on my router for my Sonos Device (i am assuming i have to create one for each of my devices) do i use my public port (in plex) as my external port for port forwarding and my private port as my internal port? Do i also require TDP, UDP or both? Cheers

    Sorry, not a IT savy but it is really a nonsense to use NAT hairpin/loopback to play local content on Plex.

    Why doesn't Plex refer to this NAT issue in their walkthrough?

    I have manual port forward working fine and have no problems accessing my Plex server remotely. Plex on Sonos has never worked however. My router doesn't support this NAT reflection option so guessing thIs is probably the issue most people are facing.

    Have Plex acknowledged this problem and whether they are trying to develop a workaround?

    Plex hasn't acknowledged anything except that they're "working very slowly" on the Sonos connectivity at this time (that was as of March 8th 2017). They seemingly abandoned it within days of its release with only one Plex employee posting just a couple of times in this forum since the release about a year ago now.

    I had issues connecting to plex. I finally realised that if instead of going through the menu that first appears in the sonos application, if I select Other Libraries at the main menu, then click the plex server name where the music is stored on, then click on the folder where the music is on your plex server it works, it seems the authorisation process doesn't select the correct plex server if you have more than one.
