Which of the following allows you to capture packets at four inspection points as they traverse a Check Point gateway?

Carlos M.Jun 12, 2026

D is your answer. fw monitor is Check Point's built-in packet capture tool and it hooks into the firewall kernel at four specific inspection points: pre-inbound (i), post-inbound (I), pre-outbound (o), and post-outbound (O). That lets you see exactly where a packet is being dropped or modified as it moves through the gateway, which makes it way more useful for troubleshooting than a generic tool like tcpdump. tcpdump only sees traffic at the interface level and misses what happens inside the Check Point kernel chain, so it would not show you all four points.

I initially circled A because tcpdump is what I reach for on Linux when I need raw packet capture, but then I remembered that tcpdump on a gateway only sees traffic at the OS level and has no concept of the inspection chain. fw monitor is the one that gives you those four capture points, pre-inbound, post-inbound, pre-outbound, and post-outbound, so you can actually watch a packet move through the SecureXL and firewall layers, which is exactly what you need when you are troubleshooting policy or NAT issues on a CloudGuard gateway.

fw monitor is the right call here. It hooks into the kernel at four capture points, pre-inbound (i), post-inbound (I), pre-outbound (o), and post-outbound (O), so you can trace exactly where a packet gets dropped or modified as it moves through the inspection chain.
