Which CLI utility allows an administrator to capture traffic along the firewall inspection chain?

The tool that allows an administrator to capture traffic along the firewall inspection chain is fw monitor. This utility is specifically designed to provide detailed visibility into the traffic flowing through the firewall, making it invaluable for troubleshooting and understanding how packets are processed and inspected by the firewall. Unlike other utilities, fw monitor captures packets at various points in the security processing chain, allowing the administrator to see the state of packets as they pass through the layers of inspection, including all relevant components of the Check Point architecture.

Tcpdump is a powerful tool for capturing traffic on a network interface, but it does not provide the specific context of the firewall inspection chain, which is crucial for understanding how traffic is processed in a Check Point environment. Similarly, while tcpdump and snoop can be useful for general network traffic analysis, they do not offer the tailored insights required for firewall-specific operations that fw monitor provides. Therefore, fw monitor is the go-to utility for capturing and analyzing packets in regard to firewall inspection processes.
