While the assumption of BT is generally correct, the source and the dest
is both Teredo, as such it should not go over his box in the first place.

But, as we do not know if he has a default route or anything else on it
it is hard to tell why his box is even forwarding these packets.

I do hope that proper RPF checks are in place...
