Thanks for the off-list replies. Think I've got the issues figured out.
6rd behaves a lot like 6to4 in how it handles traffic destined for hosts
in the same ISP IPv6 subnet - and aggressive filtering of protocol 41 on
external facing interfaces can break that.
RFC5569 has more details on implementation, in case anyone else runs
into this problem at a later point.
