VMware Player blocks Teredo IPv6 on Windows 7

It seems VMware Player blocks Teredo IPv6 on Windows 7:

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.

VMWare Player used to not block it...when I used it a few years back to test with. That was on XP but...IPv6 would only work on a VM if I had the XP IPv6 stack loaded. VMware Server has no issue. Lots of IPv6 on VMs here.
