Hello,
I create a socket for broadcast by

dhcpSocket = socket(PF_PACKET, SOCK_PACKET, htons(ETH_P_ALL));
setsockopt(dhcpSocket, SOL_SOCKET, SO_BROADCAST, &flags, sizeof(int *));

and send a message by

sendto(dhcpSocket,&UdpIpMsgSend,sizeof(struct packed_ether_header)+
    sizeof(udpiphdr)+sizeof(dhcpMessage),0,
    &addr,sizeof(struct sockaddr)

then receive a replied broadcast message by

recvfrom(dhcpSocket,&UdpIpMsgRecv,sizeof(udpipMessage),0,(struct sockaddr
*)&addr,&i);

It works well on normal LAN. But on a wireless LAN the message
which was sent by the socket. is received from itself.
Should a message sent by broadcast socket be recieved by itself?

Thanks in advance.
