I had a "tech expert" visit not today he was next to useless clearly had no idea what Ipv6 even is when I asked him to check the Home hub logs he looked Blankly at me and again truly had no idea what I meant I just wanted him to check there's nothing else amiss with the home hub hopefully I have solved the problem now and can rely on it like so many others who are working from home</P> Sun, 05 Jun 2022 14:57:54 GMT blueingreen79 2022-06-05T14:57:54Z https://community.bt.com/t5/Home-setup-Wi-Fi-network/default-ipv6Allocation-mode-ipv6-preventing-vpn-connection/m-p/2235281#M196389 <P>Is it possible that a recent firmware update could have changed the default allocation made for ipv6 to stateless?
