Order of Precedence for Rules

As you define new rules, they are added to the tables in the Rules menu as the last item in the list, as shown in Figure 4-1:

Figure 4-1

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 may 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 button allows you to relocate a defined rule to a new position in the table.

Setting LAN WAN Rules

The Default Outbound Policy is to allow all traffic to the Internet to pass through. Firewall rules can then be applied to block specific types of traffic from going out from the LAN to the Internet (Outbound). The default policy of Allow Always can be changed to block all outbound traffic which then allows you to enable only specific services to pass through the router.

To change the Default Outbound Policy:

1.Select Security from the main menu and Firewall Rules from the submenu. The LAN WAN Rules screen will display.
