authorize{
	if (!NAS-Port && ("%{tolower:NAS-Port-ID}" =~ /([a-z])([0-9]+)/i)) {
		update request {
			Tmp-String-0 := "%{1}"
		}

		update request {
			Tmp-Integer-0 = "0x%{hex:Tmp-String-1}"
		}

		update request {
			Nas-Port := "%{expr:( %{2} * 100 ) + %{Tmp-Integer-0}}"
		}
	}
}

DEFAULT		NAS-Port >= <bar>, NAS-Port <= <bar>
