Order of Precedence for Rules

As you define new rules, they are added to the tables in the Rules screen as the last item in the list, as shown in the LAN WAN Rules screen example in Figure 5-1.

Figure 5-1

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 bottom. In some cases, the order of precedence of two or more rules might be important in determining the disposition of a packet. For example, you should place the most strict rules at the top (those with the most specific services or addresses). The Up and Down table buttons in the Action column allows you to relocate a defined rule to a new position in the table.
