Using the ASUS RT-AC68U and having NAT problems/Can't hear friends with 2 Xbox One

Router & Modem make/model: ASUS RT-AC68U

Wired or wireless: One Xbox One is hooked wired while the Second Xbox One is hooked up wireless through the 5 ghz network

Multiple consoles on the same network (Yes/No):
Yes, 2 Xbox One

I have tried the NAT troubleshooting, port triggering, etc and I am still having troubles with the Second Xbox One. My Xbox One, the first one has Open NAT and I can hear all my friends with no problems. However when my son gets on, with the Second Xbox One,
he has Strict NAT and can't hear his friends. We are able to play on Titanfall together. I have been messing around with the settings but I have no luck. I don't see my model number listed so I was hoping maybe someone else has figured out the correct configuration
for this router. Thank you.

NAT Problems- Sometimes Open, Most Times Moderate, Help

Hi, I have been having problems with the NAT not being open at all times. I am using an ASUS TM-AC1900, which is a T-Mobile modded ASUS RT-AC68U.

I have two Xbox Ones on this same network (brother and I). Both systems have the same problem.

UPnP is enabled.

No Port Forwarding atm, and no DMZ setup. Will this work when there are two systems on the same network?

I have the AC66U and under the Wireless settings, General tab, next to Wireless Mode, there is a checkbox for "Optimized for Xbox". There really isn't a lot of information about what this does, but have you tried this? Mine is wired to the One, so I don't
have this enabled.

 

If you haven't resolved this, try my solution for the very similar problem I was having with my Xbox 360's:

You really don't need to set up static IPs or port forwarding. You need to ensure UPnP is enabled on your router as well as setting up QoS to give the Xbox Live Network ports the Highest Priority. This change changed my NAT from moderate to open without
having to forward any ports.
