The differences between the two address ranges is probably the /56 one
is for your LANs while the :ad00: one is for your PPP link.
You're not blocking icmpv6 are you? This may stop the RA's from actually
coming into your computer. If you want to be extra picky, you could
limit the icmpv6 from link local addresses.
Also, do you have autoconf sysctl parameter enabled? You need both the
accept_ra and autoconf set to 1.
