Maybe this is pretty old for 1.4.0, but it may help you. I wrote several years ago a NTP server, NTP uses the same port for source and destination in most cases, which is 123/UDP. This is what I used: Bind, so use source port = 123: udp_bind(n->udp_socket, IP_ADDR_ANY, 123); udp_recv(n->udp_socket, ntp_net_recv_callback, n); Send to using port 123 as destination, on the same socket, so source and destination port = 123: udp_sendto(n->udp_socket, pkt_buf, ntpserver, 123);
