Detailed explanation-1: -Rules are run in priority order from highest (Priority 4) to lowest (Priority 0). Within a specific priority level the rules are processed in order based on the rule action (Force Allow, Deny, Allow, log only).
Detailed explanation-2: -Firewall rules have a priority order that determines the order in which the rules are applied to network traffic. Firewall rules are shown as a list on the Rules page. The rules are applied from top to bottom, and the first rule that matches the traffic overrides all the other rules below.
Detailed explanation-3: -The relative priority of a firewall rule determines whether it is applicable when evaluated against others. The evaluation logic works as follows: The highest priority rule applicable to a target for a given type of traffic takes precedence.
Detailed explanation-4: -The first rule allows all traffic to port 80 on host 1.2. 3.4 to go to a web server as legitimate traffic. All other traffic on that network segment is dropped. If you reverse the rule order, all traffic to the segment is dropped, even the traffic to the web server on 1.2.
