FW monitor is a great tool for troubleshooting traffic flow issues with your checkpoint.
It works by using 4 inspection points,
- i – Pre Inbound
- I – Post Inbound
- o – Pre Outbound
- O – Post Outbound
Examples
- fw monitor -e “accept dport=6000;”
- fw monitor -m iO -e ‘accept dport=80;’
- fw monitor -e ‘accept dport;’ -o ping.cap
