You need to make sure that your router supports multicast.

Code to Join:
struct ip_mreq mreq; // mreq is the ip_mreqstructure { struct in_addr imr_multiaddr; //The multicast group to join struct in_addr imr_interface; //The interface to join on } #define RECV_IP_ADDR "225.6.7.8" // An arbitrary multicast address mreq.imr_multiaddr.s_addr = inet_addr(RECV_IP_ADDR); mreq.imr_interface.s_addr = INADDR_ANY; err = setsockopt( sock, IPPROTO_IP, IP_ADD_MEMBERSHIP, (char*)&mreq, sizeof(mreq));Igor Proskuriakov
