IPV6/Teredo on Windows XP SP2 or higher RRS feed

  • Question

  • I have been reading all day to get my Windows XP SP2 to work with Teredo. But all information I found are about Windows XP without service pack. So I cannot figure out the problem.

    What I am trying to do is I am trying to run .NET Framework 4.0 based NAT Traversal. I make a small application to do the NAT traversal and when I run the Code on Windows 7 it works fine almost out of box. i.e. I didn't adjust anything on my Windows 7 machine, just write a code and start the server and get connected from client. Easy.

    But when I run the CLIENT code on Windows XP sp2 it fails, because my XP machine generate the error that it cannot reach the 2001::__ based IPv6. Specific error is "Destination address is unreachable".

    What I did is:

    1. I install netsh int ipv6 teredo install

    2. I set the teredo.ipv6.microsoft.com as Server address

    3. I ping ipv6.google.com but got "Destination host unreachable"

    4. When I tracert6 ipv6.google.com, I got Request Time out for hob Addresses.

     

    Since I am using XP sP2, we already have Advance networking pack installed. However I cannot see IPv6 ICF in Windows firewall and for matter I just disable the firewall on my test machine.

    Any idea how can I get it running ? Thanks

  • Check the teredo status by typing the below cmd:

    netsh int ipv6 show teredo

    If ur behind symmetric NAT then u need to enable port forwarding

  • Sorry for late reply. But on Windows XP sp2 it doesn't show us anything, infact it show us Offline. However Windows 7 or Windows Vista on same network shows us Restricted NAT or sometime Symmetric NAT. [it shows different state every 4-5 hrs].

    However the question is now irrelevant for me, as my client opt to leave Windows XP from our software need. But I still love to see if this thing work on Windows XP or not, so any help is good to have.
