Hi Micheal,
  Thanks for your email. Yes I did your changes. I do get
ping6 ::1 and
ping6 ::163.143.99.101 and to all other v6 hosts on 99 subnet. But
I do not get
ping6 3ffe:501:427:1000::163.143.99.101 and others.
For ping6 www.6bone.net (external 6bone host) it gives network is unreachable,
but for local hosts no reply.
I tried to ping6 from the tunnel provider , the same result (I checked
with tcpdump6, icmp v6 messages are transmitted on eth0),
ping6 ::163.143.180.107 works but not the global address.
  Thanks in advance,
