Packet Flow in Checkpoint Firewall

Jump to solution

Hello All,

I am very confused with the packet flow of checkpoint firewall. I have seen in many places fw ctl chain is referred to understand the packet flow but I am not able to interpret it.

Could someone please help me in understanding the packet flow in terms of

SAM

IP spoofing

Policy lookup

Dst NAT

route lookup

Src NAT

VPN

etc..

Even better if we can connect it with the output of fw ctl chain

I would really appreciate any comment.
