Dear Sir, I have to create a route program for my thesis. Its operation is different from normal packet forwarding. Therefore, I need to forward all packets instead of using normal packet forwarding in FreeBSD kernel. I capture packets via Divert socket. It works well. I can grap IP packket including its header. However, I use normal Raw IP socket to write the packets to selected next-hop. I use socket option SO_DONTROUTE and IP_HDRINCL with my Raw IP socket and use "sendto" to write packets with "sockaddr" set to the IP of the next-hop-gateway. The sendto command always return error with errno=22. How can I solve this error? Thank you for all help.
