Hello,
I've started to use IPv6 on Debian Lenny. To do so I set up an HE-/64 Tunnel
an registered an a routed /48 block
tunnel is: 2001:470:1f14:1460::/64
Routed block is: 2001:470:d600::/48
The tunnel is running fine - and I can Ping ipv6 hosts outside.
he-ipv6 Link encap:IPv6-in-IPv4
inet6 addr: fe80::ac10:f801/64 Scope:Link
inet6 addr: 2001:470:1f14:1460::2/64 Scope:Global

Furthermore I assigned a /64slice of 2001:470:d600::/48 to dummy0

and set up raddvd to announc auto-configuration
interface dummy0
{
AdvSendAdvert on;
prefix 2001:470:d600::1/64
{
};
};
routing seems to be running fine and I can reach 2001:470:d600::1 from the
outside

dummy0 is assigned to a vmware-bridge, that is connected to a debian lenny
guest.
The guest got its radvd announce and set up his interfacse:

The interface itself is running fine, the guest is able to ping 172.18.0.1
(IPv4 address of host), but he's not able to ping6 2001:470:d600::1.
Even more, the guest seems to be unaware of his neighbor:
ping6 2001:470:d600::1
PING 2001:470:d600::1(2001:470:d600::1) 56 data bytes

What might be wrong here?
Thanks in advance,
