I wonder to which box (IPv4) behind the NAT it is forwarding
the proto-41 packets then. Unless you configured a default/unmatched
target ofcourse. But then you already configured it correctly ;)

If you are in a hotel you won't have any access to the CPE either.
And the CPE won't know what to do with the proto-41 packets when
it reaches it then. But that's why we've got Teredo. Though one
can always ask himself if it where a policy decision for not
having IPv6 in their network but let's not go there...

Greets,
