Hi,

Thanks for your reply.

Ah Okay - I though that with mobileIP support it was possible to do 
IPv6-in-IPv6 tunnels - I don't seem to be able to get the iptunnel/ip tunnel 
commands to accept an ipv6 address.

Though actually what I am trying to do is set up a double tunnel - with the 
outside being IPv6-in-ipv4 carries a IPv6-in-IPv6 tunnel. How would one 
achieve that? I've managed to set up the IPv6-in-ipv4 tunnel without problem 
but as I mentioned above I don't seem to be able to set up the "inner" 
IPv6-in-IPv6 tunnel.

Great. I will see how I get on.

Thanks,

Piers.
