A packet filter consists of a list of rules. Rules are listed in the order of priority. To change the priority of
rules in the list, click the up or down buttons in the Order column. Rules may be added or deleted.
When creating a new filter, rules must be added. Using the "Add new rule" button, enter each new rule as
required.
