Hi All, Is it possible to redirect/send/divert a bpf packet capture of one interface to a listening tcp socket on another interface of the same machine? Here is my problem: I'm capturing packets on one interface but for some specific tcp packets let's say from host A to host B on port P, I want to hijack the packet and send it to a listening tcp socket on the other interface and reply an "Access Denied" message. I'd like to use the tcp socket on the other interface as it's not possible to communicate over the interface that's doing the packet capture and I don't want to invent the wheel by doing all the tcp/tcb states hence using a tcp socket. Thanks a lot Alireza
