Yes, its enabled.
I set it up as Native. Now I am getting IPV6 for DNS. But its not the DNS server IPV6 instead its the IPV6 which see under IPV6->IPV6 Lan Setting -> Lan IPV6 Address. I have configured Cloud Flare IPV6 but instead I am getting Lan IPV6 address.
And I have one more...
Hi
I have changed my router to Asus AX88U and install latest merlin. I tried to enable IPV6 for my XBOX-X but for DNS its still using IPV4 address.
I have tried the same in OpenWRT routers and I get IPV6 for both console and DNS.
In Merlin, It looks like I am making some mistake.
Anyone...
