Strict NAT since isp enabled IPv6

I have been with sky fibre pro for a couple of years and my Xbox one has always had an open NAT, Friday night sky enabled my line to have IPv6 and since then my NAT has been strict. Is there any way of making it open buy changing setting etc ?

any help would be great.

I can't play online on Gta V but i have Gold

Not all IPv4 connections are strict and even if the NAT type is strict it can be opened. - There is no need to upgrade to IPv6

Perform a network test from your xbox console. If you get IPV4 that means strict NAT and you need to upgrade to IPV6.

is the Sky in bridge mode ? if not , your using 2 routers it seams.....I would plug the xbox straight into the sky sr102 , reboot everything and test nat again....also , I recall lots of issues with those sky hubs in the past....

 

and , can you disable the ipv6 ?

 

I can disable IPv6, but would much prefer to run it on IPv6 if I can. The sky modem is not in bridge mode and the Asus router is set to wireless router mode.

 

bypass the Asus and plug into the sky....If the sky is not in bridge , then it is also still a router and you will get double nat ....

 

Can not set sky hub to bridge mode. I have managed to get my nat open using IPv6, in my sky hub I went to security, firewall rules then enabled the IPv6 firewall and my nat is now open. It quotes the held section of the inbound services -

"Inbound Services Enable Inbound IPV6 IPSec Firewall: This option will enable/disable only the IPsec related inbound IPv6 firewall rules in router. It is independent of the Enable IPV6 Firewall option.

Enabling this option allows devices to use IPv6 natively to improve connectivity to services like the Xbox On"
