    I am on a camping and there is Wifi. Natted of course. The signal is too weak for the PCMCIA card in the laptop and so I pick it up with a directional antenna connected to a WiFi bridge in client mode. To share it with others on te same field, I feed it to the WAN port of a wireless router. So the users that link through me are behind a double NAT.

    That works for BINKP, http, POP3, smtp and other protocols. Not for Teredo.

    Teredo does not work behind a double NAT.

    So I eliminated the second layer of NAT by configuring the router in bridge mode. Now teredo works. My ipv6 is 2001:0:4137:9e76:0:78f8:a3b9:dc0c. It is pingable when my laoptop is on.

    To my surprise I get a 10/10, 9/10 from test-ipv6.com. I expected a lower rating because Teredo s not the best of the best. I can't do an ipv6 speedtest because http://ipv6-speedtest.net/ reports that I do not have ipv6. No surprise because IE8 uses ipv4 when the ipv6 connections is via teredo.


    Cheers, Michiel

    firefox works with teredo

    are you sure ie8 does not just prefer ipv4 over ipv6 ?

    where is the open source manuals to netsh ?

    Nope. IE8 does not "just" prefer ipv4 over ipv6.

    It prefers ipv6 over ipv4 when the ipv6 connection is native or via a configured tunnel. (6in4 or ayiya). It prefers ip4 when the ipv6 connection is via an automatic tunnel. (teredo ot 6to4)
