When connection is set to use passive mode, TC sends EPSV to server and immediatelly (no delay at all) follows with EPRT as if establishing passive data connection with server failed. But according to packet sniffer, TC does not try to establish the connection at all, no packet leaves the machine for port returned by server. Active connection then gets established without any problem.
