Viewing Rules and Order of Precedence for Rules
To view the firewall rules, select Security from the main menu and Firewall from the submenu.
The LAN WAN Rules screen appears (Figure 4-1 shows some examples). As you define new
rules, they are added to the tables in the Rules menu as the last item in the list.
For LAN WAN rules, DMZ WAN rules, and LAN DMZ rules, for any traffic attempting to pass
through the VPN firewall, the packet information is subjected to the rules in the order shown in the
Outbound Services and Inbound Services rules tables rules tables, 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 (see below).
