The 1st three lines block the unwanted portions of the ranges allowed by the last 2 lines. Don't forget the implied deny all after the last line that blocks all other addresses. Some folks like to put an explicit "deny any" as the last line. Can be applied inbound on the external interface(s) or outbound on the internal interface(s).
