IPv6 problem on Windows Server 2008

[snarked]

Aside -

Link-local IPv6 Address . . . . . : fe80::5efe:192.168.1.10%13(Preferred)

WTF?

That's not a legal IPv6 address format.  A textually-embedded IPv4 address in an IPv6 literal is valid only in two /96 subnets of ::/80.  Micro$oft definently screwed up if they think otherwise.

Looks to me as if you've got a wrong address on the wrong interface.  Why is any 2001:470:27:19f::/64 address appearing on your wireless interface?  A single address from that subnet should be ONLY on the tunnel interface.  See what it does to your routing table?  That's why nothing goes out.
