Hi All, I need a little help with FreeBSD Kernel stuff. I wanna use Divert Socket t= o sniff IP packet in FreeBSD. For that I have compiled the kernel with options IPDIVERT and everything is ok. Now, when I am not really sniffing and re-injecting the packet back to the network stack, it is basically dropping all the packets. But I want it pass-through it, when no application is reading at divert socket. My question is, HOW CAN I MAKE IT PASS-THROUGH? IF NO APPLICATION IS READING FROM DIVERT SOCKET, IT SHOULD WORK AS IF THERE IS NO DIVERT SOCKET.
