Enabling IPV6 on SOHO 3

Hi - I have a SOHO 3 with 7.1.1 Firmware and an OpenReach HG612 modem. I’m struggling to get IPV6 working (needed for MS Direct Access). Does SOHO support IPV6 - and if so, is there anything I need to configure?
Thanks

Is there information as to when ipv6 support will be available for the Surf SOHO mk3?

Is anyone monitoring these threads? If so, is there any information on this, Peplink?
