Access Plex behind Double NAT at Local Network

General Discussions

Hi Guys,

My ISP Modem also has a DHCP wifi which happens to sit near my kitchen, but I never use it, I am using my AirPort Extreme for all my devices and I have set it up to DHCP mode because I prefer IP (10.xx.xx.xx instead of 192.xx.xx.xx) (hence facing double NAT)

So long story short, I have noticed that (AirPort Extreme) wifi speeds are terribly slow in the kitchen and Plex really struggles in there.
Now when I connect to this ISP modem wifi, it is not able to detect Plex locally, it shows as remote connection.

Is there some network settings in Plex that I can do to bypass this and make Plex locally available on the ISP Modem (after all ISP modem and AirPort Extreme are connected via ethernet)

Thanks

It’s 2 different networks as far as networking is concerned… You won’t be able to do the local connection with it setup as a Double NAT.

Out of curiosity, what is your aversion to 192.168.x.x addresses?

Double NAT will always give you a world of trouble, in many situations.

Did you know you can configure your AirPort Extreme to operate as a basic access point? It won’t do any NAT or DHCP in this mode and will eliminate your double NAT problem. Worth reading up on and giving it a try, imho.

How is your machine running Plex Media Server connected to the network, out of curiosity? Is it connected to the 10.0.0.0/8 network on your AirPort Extreme or the 192.168.0.0/16 on your ISP’s equipment?

(Also, it’s not 192.xx.xx.xx, it’s 192.168.xxx.xxx. That’s your class B RFC1918 subnet. As @JasonNalley alluded to: there’s really nothing to choose between the three networks (there’s 172.16.0.0/12, too) as they all do the same job, just with different sizes of IP address space)
