The silent premise in this request is that all student Internet access
occurs through the school's gateway.  Which is of course false.

If the objective is to prevent misuse of school resources for
non-education purposes then the premise, while faulty, is fine.  If
the objective is to restrict students' Internet access in its entirety
then this is doomed to fail.

Have you clarified with the director that only access through your
gateway can be affected by this policy and that student devices with
cellular data plans will still have access?
