What needs to be changed to see all the traffic passing through a firewall rule during troubleshooting?

To see all the traffic passing through a firewall rule during troubleshooting, logging firewall traffic is essential. This logging option allows for a comprehensive view of every packet and connection that matches the criteria of a particular firewall rule. By enabling this feature, network administrators can capture and analyze the flow of data, including the source and destination IP addresses, ports, and protocols used. This visibility is crucial when diagnosing issues, as it helps identify whether packets are being allowed or blocked based on the set rules.

While other options may provide insights into different aspects of network activity, they do not specifically address the need to observe all traffic through a firewall rule. For instance, logging application activity focuses more on the behavior and usage of applications rather than every packet’s journey through the firewall. Additionally, enabling SSL inspection is important for decrypting encrypted traffic, but without logging firewall traffic, the visibility gained from SSL inspection would not be as effective in revealing the fundamental flow of all traffic relevant to the rule in question. Monitoring user activity provides insight into user behavior and access patterns but does not give a complete picture of the traffic passing through the firewall rules. Thus, logging firewall traffic is the most direct and effective method for the task at hand during troubleshooting.
