Teredo Tunneling Queries RRS feed

  • Question

  • Hi everyone. I am a P2P developer facing some problems, expecting your help.


    My pc is currently using 6to4 tunneling protocol to connect to IPV6 network. I want to  change it to Teredo, b'coz another peer is using teredo. Plz tell me the procedure either using netsh commands or else. I am using Windows XP SP2.

    Hi Sandeep,

    If your machine is a domain joined, you need to enable Teredo explictly using following command.

                  netsh interface ipv6 set teredo enterpriseclient.

    Teredo is a transition technology which tunnels IPv6 traffice over IPv4 UDP packets. You need to configure your edge Firewall accordingly. You can find more information on Teredo at.


    The Teredo prefix is 2001::/32. If you are in XP and the Teredo prefix is 3FFE:831F::/32, then you need to install the MS06-64 update.

    If you have already installed the PNRPv2 update in XP, that already took care of MS06-64.

    Please let me know if you need some more information.
