Hi there.
I recently changed from a business acc to residential acc with my ISP in NZ(2degress) and found from reading your forums that I was having a DOUBLE NAT problem (the IP address in the settings on the ‘gateway’ was different from that IP address found by WHATSMYIP website).
Symptom being I was unable to get plex ‘remote access’ to stay connected even though it said it wasand it would slip back to “indirect”.

So turns out that their residential accounts are all behind a CGNAT and the only way I could get remote access to stay “connected” was to have a static IP.

So my Q isdoes EVERY plex user in the world who uses remote access have a static IP?
Or is there a way around it?
Have I just been duped into paying extra for something I don’t need?
cheers for your ideas. CD

Yes CGNATyou don’t need it. There are a couple ways you can go.

For myself I requested my ISP to Opt out of CGNATsecondly is purchase a Static IP which in Australia is $10 monthly.

I would go down the road of Opt Out as it should be Free. Just remember when they switch it off to restart your Fibre connection BoxRouter and Server. They should be able to do it Live/ straight away.

hi there
how does one “opt out”?
is it a setting or a contact the ISP kind of thing?

Contact your ISP and request Technical support.

Your Welcome.

Mention it is required for Remote connections.

BasicallyRather than have one of the increasingly-scarce public IP addessesyour ISP gives your router a private IPand routes all your traffic through a router of their ownand THAT router is the public-facing router with a public IP.

I’m lucky to not have an ISP that does CGNAT. My router has a public IP addressso I do not need to request a static IP address. TECHNICALLYif I were to reboot my router I would get a brand new public IP from the pool that my ISP has. Plex (the company) is usually pretty good at detecting that my house’s IP changedand updates it in their systemso that the next time a client connectsthey get the new IP of my house automatically. I also own a domainand use a form of DDNS to update that domain with my current IP every 5 minutesso I told Plex to use my domain as well.

NONE of this helps you however. Call up your ISPand ask about getting out from their CGNAT. If you can “opt out” of itthat’s great. If you have to purchase a static IP from your ISP in order to be out of itwellthat’s what you have to do. There is nothing a server behind a CGNAT can do to allow unsolicited inbound traffic (like a Plex client streaming your media) to workit’s your ISP.

Thanks all for your input. I tried but they do not allow an opt-outso there it is. Irony is that I was trying to save a few $ by moving to a cheaper packageand now paying for a static IP has reduced that saving. It was free with the business acc.

IPv6 at some point will sort this outhowever currently if the following is true it could be something to look into:

1 - Do 2degrees offer a reasonable static IPv6 address space (most ISPs in Australia do)
2 - Do you have the ability to have IPv6 from client to server when out of the house (dual stack)?
3 - I’m not sure about this onehowever my reading indicates that Plex may have removed IPv6 support in the New Experience clientsso if you just need Plex Desktop Players this might work

Seems some people have been able to set up Tailscale (a VPNish system) to bypass CGNATs. I haven’t looked into itbut by the sound of it you set up a Tailscale program on your computer that calls out to Tailscale (the company) and it develops a tunnel from your house to the company. Nowanyone can hit the other end of the tunnel (the Tailscale end) with a client and they end up inside your network.

If this works the way it soundsit might even bypass the “remote streaming needs a Plex Pass” restriction… :thinking:

Edit: Forgot to link the reddit post that describes how to do Tailscale for Plex:
