I managed to get my hands on one these routers; BT HOME HUB 5 TYPE A with LEDE installed, I managed to get internet connectivity using the helpful guide, using the WAN port, the only issue is how do I get the IPV6 side running in conjunction with the LAN, and WAN?
Does anyone who's on Sky Fibre managed to get IPV6 working in the Interface options.
Not checked recently but sky didn't provide DNS via ipv6 hence using Google's.
The 'norelease' option helps keep the same prefix across router reboots.
There's no point in trying to get a specific ipv6 address from Sky, they won't give you one, but they do delegate a /56 to you.
Incidentally there's an equivalent 'norelease' style option for ipv4 which also helps retain IPv4 address across reboot.
