How to request ipv6 prefix?

Remuflon
I have successfully gotten UTM started with IPV6 / Comcast.
They gave me a /64 prefix.

According to Comcast, to get a /56 prefix, just specify it in the IA_PD option.  But where do I do that with Sophos UTM?

    OK, if no one knows how to request an ipv6 prefix then let's try it a different way.

    Since I only have a /64 prefix from my ISP, I'm creating ipv6 subnets that are /84.
    Is this going to cause problems?  If so, why?

    it wont work, /64 is the recommended minimal subnet size of ipv6.

    ipv6 is not 100% supported on sophos, lots of stuff missing like proper IPv6 over PPPoE Support.

    You can use NAT for IPv6 so you can just use private adresses internal.
