What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Not sure if IPv6 ever worked well on the R8000.
All NG routers have NAT.
IPv6 isn't required for gaming though...
If you have two game devices playing same game at the same time, try setting NAT Filter to OPEN on the routers web page.

Thanks for the response.
At the time of writing the NG Nighthawk operates firmware: V1.0.5.88_10.1.88
NAT was set to secured. I have changed this to 'Open' as recommended. Will see if this improves the situation or not.
The second router, is a Sagemcom F(a)ST3864AC (DHCP and W-Fi Disabled) and is connected on the LAN side (internal side) of the NG Nighthawk. The Sagemcom operates only as a UNI-V (FTTH phone service) enabler - due to it having the correct hardware connection points (RJ-11) which are not available on the NG Nighthawk for this purpose. All that to say, the Sagemcom Router should not be influencing the situation in anyway.
Local Area Network (LAN) endpoints pass solely through the Nighthawk as the Network Gateway. The NG Nighthawk also serves as the DHCP Server, with all other endpoints connecting LAN via Wi-Fi go through to NG Nighthawk, or, for fixed/wired LAN devices, via internal home conduit (CAT6E) cable runs to a dumb 'Harmonica' patch panel, into a TPLINK TL-SG1016D 1GB Switch, which connects to the LAN side of the Nighthawk and serves as the Core Switch for the LAN.
The Nighthawk gateway's WAN port is connected via dedicated CAT63 conduit to a dumb 'Harmonica' patch panel point, into the UNI-D activated port on the home "NBN Co" supplied Network Termination Device (NTD), which then connects into the wider Public Service Telephone Network (PSTN) via Fibre To The Home (FTTN) architecture.
Its troubling me that the NG Nighthawk is not identifying the IPv6 settings. Accepting that it like never 'worked well on the R8000', is there anything that I am doing wrong that could influence it not working?
