Seen same issue with XB settings reporting OPEN NAT and BO3 reporting Moderate. We believe it's a BO3 issue and nothing to do with router settings in most cases. I recommend doing a factory reset and also doing a console reset as well on all consoles to see. Ensure consoles are LAN wired to the router.

You might try to set up a port forwarding rule for each console, set one for 3074 and the other to 3075. Disable uPnP on the R1. Set up a Reservation IP for each xbox. Do the XB1 reset using both triggers and bumper buttons. Turn OFF both consoles. Ensure the R1 settings are set up well the reboot the R1. Turn on 1 console and check NAT status. Turn on the next one and check NAT status there. You might turn off both then reverse turning on the other console first to see if the behavior keeps or tracks. On a non R1 router I have, I used to set QoS up for 1-65535 for ports and point that to the IP address range for the consoles, i.e. 192.168.#.198 and .199 which were reserved for both consoles. uPnP would just handle the ports needed as each console was turned on. Worked like a charm there. Not sure if R1s FW allows for this kind of configuration though.

If you have uPnP enabled and you have more than one say BO3 game console connecting to the router, say 3 game consoles, uPnP should pick 3074 for the first console that connected then uPnP should be picking up a virtual port for the next two consoles, unless specified by using a port foward rules for each console, then uPnP should be disabled. I think this should work this way.
