In which order are firewall policies processed on a FortiGate unit?

The order in which firewall policies are processed on a FortiGate unit is from top to bottom according to their sequence number. This sequence number dictates the order of evaluation for the policies, meaning that as traffic flows through the firewall, it starts checking from the first policy and continues down the list until it finds a match or reaches the end of the policy list.

By organizing policies in this manner, network administrators have the ability to prioritize which policies have precedence over others based on their positioning. It allows for fine-tuned control over traffic management and security measures. If a policy that matches a particular traffic flow is found, further evaluation stops, and the defined action for that policy is applied. Therefore, understanding the importance of the order of policies is crucial for effective configuration and security management on FortiGate devices.

While other options such as best match or priority value might seem relevant in different contexts, the specific processing order for firewall policies on a FortiGate unit is strictly defined by their sequence numbers, which determines how policies are evaluated against network traffic.
