Hello,

For context I have ran 2 Plex servers off of one network for 6+ years with no issues but as of a couple days ago I have had this issue with no change from my end. Does anyone have a work around for this other than contacting my ISP witch Plex talks about when I hit learn more. Has anyone seen this issue before. Thanks

    Here’s how my setup is to avoid double NAT:

    ISP Gateway (Full pass-through to WiFi router, sometimes referred to as DMZ) —> WiFi Router (WAN address shows internet IP, not a local IP) (and this router is set up to port forward the Plex port to the Plex server) —> Plex Server

    Typically Double NAT occurs when your ISP gateway is providing a local IP (via DHCP from the gateway) to your router. You must guarantee the ISP gateway doesn’t get in the way of routing, which means it must pass all traffic directly to the router.

    I am able to configure my ISP gateway via a web interface. It’s possible the ISP sent an update to your gateway that reset some settings. Or if you recently changed WiFi routers, you may need to re-point the gateway pass-through to the new router (my setting is done via MAC address and I had to do this when I changed routers recently).

    Hope this helps some.
