After changing to the BT HH4 due to some internal network changes (see previous post about issues with BT TV setup) I have come across an issue with IPv6 not being available on my BT HH4. Please see the following screenshot:
I have been on the phone with BT Support for 1-2 hours and they were unable to help me - we tried a factory reset of the HH4 and checking multiple settings but they said they couldn't provide any support.
I had previously had IPv6 working on the previous OpnSense install but I am unable to use that due to the aforementioned BT TV issues.
I require IPv6 for work as some servers I work on are only available over IPv6.
If anyone could provide any guidance on this issue, that would be great.
