This is related to the way the SecureXL kernel driver is attached to the network adapter itself. 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. It is supported to run only a single instance of FW Monitor at any given time.ĭo 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). These captured packets can be inspected later using the WireShark (available for free from (2) WarningsĪnything related to policy installation or policy unloading on Security Gateway, will cause FW Monitor to exit. The FW Monitor utility captures network packets at multiple capture points along the FireWall inspection chains. However, even though these downloads complete without error, Wireshark shows no change in this MAC address's bytes count.Check Point's FW Monitor is a powerful built-in tool for capturing network traffic at the packet level. To test Wireshark's accuracy, I then opened a podcast app and downloaded several podcasts, each 50MB in size.
I have an Android phone, and I noticed it's MAC address is also listed on this screen, and shows a total of 228 bytes downloaded. However, when I go to Statistics->Conversations, and look under the "Ethernet" tab, it shows my MAC address as the largest network user by far, even though I'm not running any network intensive tasks. From Wireshark's main screen, I select both, ensure "promiscuous mode" is checked under options, and then begin capturing packets. My computer has two interfaces, ethernet (eth0) and wifi (wlp1s0), which are both connected. I'm trying to identify network bandwidth hogs on my local office network. What would cause Wireshark to not capture all traffic while in promiscuous mode?
