[tproxy] TPROXY behavior when there is no listening socket at the target port

Hi All, If one has a TPROXY rule that redirects the packets to a local socket on which there is no one listening then the SYN packets keep getting dropped silently. Is this expected? Without knowing that this would happen my natural expectation was that a RST would be sent by local TCP. Is this by design or a bug? Thanks, - Ashwani
