Sam, there is actually an easier way to do that (if you do not need to support NT4). Open the device with pcap_open and use the flag PCAP_OPENFLAG_NOCAPTURE_LOCAL.
The sample UserLevelBridge shows the usage of this flag.

Could the filter be positioned on the Driver layer? If could, how to write the filter string and then pcap_setfilter(...)? 在2010-03-01 20:01:36，"Helmut Vaupotitsch" <[email protected]> 写道： I just filter out unwanted packets (in your case, packets sent by your app) by comparing ether.source with the MAC address of the bound adapter. Best regards Helmut fly_2u schrieb: Hi experts, There is a problem about use pcap_next_ex(...) to receive packet in Windows XP SP3. This function will be unexpected to receive the packet sent by the function pcap_sendpacket(...) in the same port. And when I use pcap_setdirection(m_pcapHandle, PCAP_D_IN) to set it, it will return -1, the error info is "Setting direction is not implemented on this platform". How could I implement the functionality that the pcap_next_ex(...) don't receive packet sent by pcap_sendpacket? Any help from you will be highly appreciated. Thanks! BR.
