Hi Paola,

(returning offline discussion to online)
my guess of the origins of your problem is that the host machine of your virtual machines is Windows, and it does not allow raw sockets, even for virtual machines. This is probably the reason why HIP-over-UDP-over-IPv4 works, but HIP-over-IPv6 doesn't. 

If you really want to do NAT traversal with HIP, please consider:
1. Using Linux (or OS-X) as the host machine (Linux live CD/USB images are available) 2. Use HIP over UDP and IPv4, and employ the relay server as instructed in the manual (the relay server requires a public IPv4 address)
Btw, your Teredo configuration is not fully functional because I can't reach your VMs, even though you can reach by yourself. 

P.S. OpenHIP has some native support for Windows.

Then I used ping6 with the server address and I could reach it. I
invoked add map command and ping6 and waited for more then a minute but
nothing happened so I stopped it:

        Hi Miika,

        I deleted the incorrect line with "hipconf" and changed the
        debug mode
        to "all". I'm sending two emails with the output of the debug
        because
        the message is too big.


    What does "lsmod|grep xfrm" give you? It should be:
    xfrm_user              35921  1
    xfrm6_mode_beet        12658  7
    xfrm4_mode_beet        12611  7


        This is the output of the initiator


    I failed to see any 3ffe::xx/64 addresses in the log. Did you forget
    to invoke "hipconf daemon add map"?

    Here's an example (please do not copy paste blindly, you need to
    change the addresses and interface names):

    server:
       sudo ip addr add 3ffe::1/64 dev eth0 # add IPv6 addr for server

    client:
       sudo ip addr add 3ffe::2/64 dev eth0 # add IPv6 addr for client
       ping6 3ffe::2 # can you reach the server?
       sudo hipconf daemon rst all # reset hipd daemon state
       hipconf daemon add map 2001:15:e156:8a78:3226:dbaa:__f2ff:ed06
    3ffe::1
       ping6 2001:15:e156:8a78:3226:dbaa:__f2ff:ed06
       <wait for one minute>
       PING
    
2001:15:e156:8a78:3226:dbaa:__f2ff:ed06(2001:15:e156:8a78:__3226:dbaa:f2ff:ed06)

    64 bytes from 2001:15:e156:8a78:3226:dbaa:__f2ff:ed06: icmp_seq=2
    ttl=64 time=29.8 ms
    64 bytes from 2001:15:e156:8a78:3226:dbaa:__f2ff:ed06: icmp_seq=3
    ttl=64 time=47.5 ms

    I'd like to see "hipconf daemon get ha all" output after this.
