D-Link DFL-600 - Manual (Page 63)

Enter a name for the Policy group in the Policy Name field. This name will
be used to reference this Policy group. In this case, we have named this
Policy group StudyTime. The schedule we created previously will appear in
the Assign to Schedule drop-down menu and is selected as the times and
days of the weed this Policy will be enforced. We want to deny access to
PCs on our LAN, so in the Action drop-down menu, we select Deny.
Clicking the Apply button will enter the Policy into the Policy group table, as
shown above. Clicking on the icon under the Edit heading will open the
following page.
