Sky Fibre and IPV6


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 on Sky, but I've got IPv6 working with BT Infinity.

You'll need two WAN interfaces, WAN and WAN6, setup WAN as usual (I think sky use some DHCP authentication rather than PPPoE)

WAN6 is set as:

Protocol: DHCPv6 Client
Request IPv6-address: Try
Request IPv6-prefix of length: /56

I'll give that a shot. I managed to get MER (Authentication) working on it to give me my IPV4 address.

Do I need to alter the LAN interface at all?

Yes - here's an extract from my /etc/config/network

config interface 'wan6'
option ifname 'eth0'
option proto 'dhcpv6'
option reqprefix '56'
option peerdns '0'
option norelease '1'
option dns '2001:4860:4860::8888 2001:4860:4860::8844'
option reqaddress 'none'

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.

config interface 'wan'
option ifname 'eth0'
option proto 'dhcp'
option release '0'
option peerdns '0'
option dns ''
option clientid 'yourskyclientidherebutitsnotcritical'
