Teredo IPv6 was working on 'my' Windows 7. However, after installing VMware Player, all IPv6 connectivity was gone: "ipconfig" showed a lot of VMware interfaces, but no Teredo IPv6 anymore.
I'm now removing VMware Player, and immediately the Teredo IPv6 interface pops up again and http://test-ipv6.com/ tells me I have IPv6 connectivty again.
I wonder whether VMware has a good reason to disable/block IPv6, or it's just 'collateral damage' ...
So for now: bye, bye VMware ...
BTW: I wonder if VMware Player also blocks native IPv6.
