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 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, before applying the default rule. 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 buttons allow you to relocate a defined rule to a new position in the
table.

Setting the Outbound Policy

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 firewall.
To change the default outbound policy, follow these steps:
1. Go to the LAN WAN Rules tab, shown in Figure 5-1.
2. Add the outbound rules you plan to use.
3. Change the outbound policy by choosing Block Always from the drop-down menu.
