Hi, Can anyone please help me understand how the IPFW firewall is implemented in the kernel. I have created new ACTIONS in ipfw. I have already implemented in the userland. Now i need to check the IPFW rule list (in ip_input.c and in ip_output.c) and call a custom routine if there is a match to those rules. I would really appreciate if anyone could point me to right direction/reference. thanks
