I figured this out now. The reason for it was that the routing advertisement 
was set for the network used by ip6 to ip4 tunnel. Thus all traffic went to 
the router to be routed to the internal network. The reason why this only 
happened on the windows machine is probably due to way the DHCP client works.

Internal: 2001:470:1f09:800::1/64
External: 2001:470:1f08:800::1/64

Anyway don't I feel stupid.
