Results from Netsh int Teredo show state:

Teredo Parameters
---------------------------------------------
Type                    : client
Server Name             : teredo.ipv6.microsoft.com
Client Refresh Interval : 5 seconds
Client Port             : unspecified
State                   : dormant

To get it into a qualified state, I used Ping -6 www.sixxs.net with the following outcome:

pinging www.m.sixxs.net [2001:838:1:1:210:dcff:fe20:7c7c] with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 2001:838:1:1:210:dcff:fe20:7c7c:
    Packets: Sent = 4, received = 0, lost = 4 (100% loss)

Subsequent Results from Netsh int Teredo show state:
Teredo Parameters
---------------------------------------------
Type                    : client
Server Name             : teredo.ipv6.microsoft.com
Client Refresh Interval : 5 seconds
Client Port             : unspecified
State                   : probe (primary server)
Client Type          : teredo client
Network               :  Unmanaged

after a couple of time the state goes to
Teredo Parameters
---------------------------------------------
Type                    : client
Server Name             : teredo.ipv6.microsoft.com
Client Refresh Interval : 5 seconds
Client Port             : unspecified
State                   : offline
Error                   : Primary teredo server unreachable over UDP

and eventually the state returns to:

Teredo Parameters
---------------------------------------------
Type                    : client
Server Name             : teredo.ipv6.microsoft.com
Client Refresh Interval : 5 seconds
Client Port             : unspecified
State                   : dormant



Can someone please point me to the mistake that I am doing.Also am ready to debug and give you all the information that you need.

Thanks a ton in advance

Answer 1

Hello Joshua,

Could you clarify if your machine is directly connected (not behind a NAT)? If so, Teredo will not work as you have a private ipv4 address.

Answer 2

Teredo is design especially to work behind NAT and even if you private IP

in the beginning it look that your computer already obtained 2001: address which is Teredo Address so I think it is only firewall problem check this link and make sure it is not firewall problem http://support.microsoft.com/kb/968510

 

Answer 3

Hi joshua,

I can see the ipv6 address with teredo prefixx(2001:...). I think ocassionally, your primary teredo server goes unreachable. You can change the teredo server address to Microsoft's teredo server in US region by ip. It can resolve the problem if ur local region teredo server has temporary problem. Type the following to do so:

netsh int ipv6 set teredo client 65.55.158.116

You can also try installing gogo6 client software, they give free static ipv6 address for personal use.

Answer 4

Its because the Teredo state is unqualified - I think this was introduced some time back as a protected mode because IPv6 can traverse stateful firewall rules if the firewall doesnt understand IPv6

To force the teredo state into a 'Qualified' state open up gpedit.msc and under Administrative Templates > Network > TCPIP Settings > IPv6 Transition Technologies; change Teredo Default Qualified to 'enable'

You should have a bit more luck then..
