Netgear Nighthawk R7000 setup for Ipv6 on Vodafone FibreX

Hi there,

I've been advised by Vodafone that Ipv6 is enabled on my FibreX connection but I can't get an Ipv6 address using the suggested Auto Config set up for the R7000. Anyone have any luck doing so? Any help would be much appreciated.

Thanks,
