I understand your router is doing 6to4 and announcing it (just like it would with ULA. or a unicast global).
My point was more to the fact that the poster had said Windows was using the built in 6to4 adapter. This is where Windows itself open a 6to4 tunnel. This is incorrect as it cannot be done behind NAT which should probably be pointed out so others browsing don't go enable 6to4 behind their router.
Ahh, OK. Thank you for the clarification.
