Hi Jon,

There are many things that don't work the same in v6 compared to
v4...

I don't use ufw so am not sure what it might do, but common reasons
for RA not working are:

- Your host has IPv6 forwarding enabled so won't listen to RA by
  default
- You've blocked ICMPv6 router-advertisement inbound and/or ICMPv6
  router-solicitation outbound.

Could either of those be the case?

Cheers,
Andy
