What is the purpose of Force Allow in firewall rules?

The concept of Force Allow in firewall rules serves a specific purpose in managing network traffic effectively. It is designed to ensure that certain predefined types of traffic are permitted, even in the presence of broader denial rules. By using Force Allow, an administrator can exclude a specific subset of traffic from being affected by any Deny actions that might otherwise block it. This functionality is crucial in scenarios where certain essential services need continuous access, regardless of the overall security posture dictated by other firewall rules.

For example, if a firewall is configured to deny all incoming traffic except for web traffic, but there is a specific application or service that also requires uninterrupted communication, the Force Allow rule can be implemented to guarantee that this application can function without interruption. This results in a nuanced approach to firewall management, allowing flexibility to meet operational needs while still maintaining a secure environment.
