Destination unreachable: Address unreachable

[schranz]

Hello !

i ask you for a probleme with my tunnel. I work with a virtual Machine in ubuntu 13.

I have create a tunnel with this configuration

Code Select Expand


# interfaces(5) file used by ifup(8) and ifdown(8)
#auto lo
#iface lo inet loopback

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
endpoint 216.66.84.42
address 2001:470:1f12:769::2
netmask 64
up ip -6 route add default dev he-ipv6
down ip -6 route add default dev he-ipv6


and i have indicated in the network card this option for ipv6
2001:470:1f12:769::1
64
2001:470:1f12:769::2

then was good but a have create a another vm with the same configuration a have have the message :
from test-1.tunnel.tserv10.par1.ipv6.he.net icmp_seq=1 Destination unreachable: Address unreachable

can you helpme to see the probleme please ?

you are using the wrong /64 for your NIC. go look at what your routed prefix actually is.

Thanks you for the reply, but i understand not your answer ?

i  have this configuration from my tunnel :

Server IPv4 Address:216.66.84.42
Server IPv6 Address:2001:470:1f12:769::1/64
Client IPv4 Address:82.248.53.3
Client IPv6 Address:2001:470:1f12:769::2/64

normally i muss asign to the NIC the server IPV6 address the netmask and the clinet ipv6 adrress ?

else can you say me whel /64 add ?

Thanks
