According to this I I should expect a /56 when I enable ipv6 on my router: http://help.vodafone.co.nz/app/answers/detail/a_id/24011/~/about-vodafone-and-ipv6
I'm using a Sophos/Astaro UTM, and when I enable ipv6, I get a /128 assigned to my external interface, which isn't quite what I expected to see: 2407:7000:f01c:0:20c:29ff:feed:a9cc/128
Can anyone tell me what I'm missing?
Doing a bit of digging, I wonder whether the /56 I'm getting is really:
I'm trying a few networks inside the firewall like 2407:7000:f01c:[1-5]:0:0:0:0 and they seem to work, so hopefully I'm not causing any issues!
Spoke too soon. I had NAT enabled, so the internal addresses weren't visible outside. When I turn NAT off, I can see traffic from my prefixes going out, but nothing coming back. Routing problem or I have misunderstood what networks I should create?
