Actually I think this is just right... Whenever a client accesses a
resource through a translator, it should be restricted not only by its
own access, but also the translator's access.

It is actually a problem that this policy is not followed whenever an
intermediate translator hands out a "real" port to another translator,
and the client reauthenticates it. (The so-called "firmlink problem".)
