Important Note: Traffic captures can be misleading when working with SecureXL since both FW Monitor and Tcpdump do not always show ‘real’ packets that are going out to the network. If SecureXL is enabled on the Security Gateway, then FW Monitor and tcpdump will show only the non-accelerated packets (e.g., ‘TCP SYN’ will be shown, and ‘TCP ACK’ will not).Packets are defragmented as they leave the Security Gateway in both the inbound and outbound directions.Do not modify Check Point kernel tables used in the security policy while FW Monitor is running, otherwise unexpected behavior may result (including a system crash).It is supported to run only a single instance of FW Monitor at any given time.Anything related to policy installation or policy unloading on Security Gateway, will cause FW Monitor to exit.These captured packets can be inspected later using the Wire Shark. The FW Monitor utility captures network packets at multiple capture points along the Firewall inspection chains. FW Monitor – Check Point’s FW Monitor is a powerful built-in tool for capturing network traffic at the packet level.In checkpoint we have three types of packet capture tools as following :
