NAT Loopback or Hairpinning? How to set it up?
Ok, This was working with Apple Airport Extreme. Initially worked with Nighthawk. Since firmware update no joy.
KB says the R8900 supports NAT Loopback but that is all it say nothing about setting it up.
The Plex KB indicates that this has to be enabled to work with SONOS, enables sonos to access Plex from inside the network, while still allowing PLEX to work outside the house.
I tried to get support. What a pain, and guess what before we got the problem solved my 90 support expired and they would no longer help me, even though my case had been open prior to the expiration.
I cannot find any way to set this up. I run Plex on a NAS, I have the NAS mapped in the PLEX area of the router.
Can anyone help me? Get deperate since I spent so much for a router that wont do the primary function I use when I am home.
Well appears to be working now.
Apparently the UPnP between the Synology and the R8900 while showing in the table was not working properly.
I went in and set up a port forward via the router. Like you indicated I set up one port to forward 32400 to the IP address of the first synology addres, then repeated for the second IP address, dual NICs with seperate IP's.
Doing this appears to have eliminated the UPnP table, but the Sonos/Plex issue is gone. It does appear that the other items setup by UPnP still work though (ie: browse to 192.168.1.250 and it works like it is supposed to from the UPnP and goes to 192.168.1.250:5001
I apologize for the incompetence but I have never had these kind of issues with previous routers. Biggest issue was always wifi strength throughout the house. Paid through the nose for this to fix that problem, and it does much better than previous routers but trying to get this working again was more than frustrating

Thanks for the prompt response
So you are saying you cannot turn on or turn off NAT Loopback?
The only NAT setting I could find were WAN, Secure, Open, Disable SIG SLG
Tried all 3 one at a time no luck
Google Nighthawk R8900 NAT Loopback, thats the KB I was referring to. All it does is list the models that will support it.
UPnP from the NAS works, though I noticed sometimes the R8900 erased the table.
Port show open from external IP
From the home network I should be able to go to external IP (xxx.xxx.xxx.xxx:32400/web)
that is not working when I try it.
All PLEX KB articles say when that happens that NAT Loopback is not enabled and that once it is changed it will work.
Have done factory reset and started over from scratch. Everything works fine except for being able to access the external IP from inside the network (at home)
Again I will ask, is NAT Loopback something that is on all the time for the R8900 so you cannot configure it? IF it is on all the time how come the external IP is not accessible?
Thanks in advance for your help!
