 Incoming packets on an interface are first checked for validity using a predefined set of checks. After that fragments are handled specifically. The first user controlled filtering stage is the supervisor rule set. Supervisor rules are often used as a coarse filter to get rid of unwanted traffic. An example of this is the so-called "spoof protection", which makes sure that an incoming package comes from a valid IP address range.
