HI,everyone<br> Recently I have come across a problem concerning winpcap sending multicast packets on windows 7 loopback adapter.<br> Here have an application with two componets.One componet is a<br>simulator using winpcap to send and receive multicast packets on<br>
windows networks adapters with fixed ip(i.e,192.10.x.x). Another is a net module using winsock's setsockopt,ioctlsocket, recvfrom etc<br>functions to receive multicast packets sent by the first componet.<br> My problem is when I use windows 7 loopback adapter with fixed ip,the first compent can send packet out(see it from the wireshark), But the net module component can't receive any packets. However, the same application really works on windows XP.<br>
I rarely know anything winpcap packet sending mechanisms with<br>windows loopback adapter.I don't know how to fix the problem under windows 7.<br> I have searched many times but gain nothing.Does anyone have the similar problem or know something or some keywords about this, please help. Thanks in advance.<br>
