Order of Precedence for Rules
As you define new rules, they are added to the tables in the Firewall Rules screen, as shown in the
following figure:
For any traffic attempting to pass through the firewall, the packet information is subjected to the
rules in the order shown in the Rules table, beginning at the top and proceeding to the default rules
at the bottom. In some cases, the order of precedence of two or more rules might be important in
determining the disposition of a packet. The Move button allows you to relocate a defined rule to a
new position in the table.
