<tt>Sure, use pcap_compile() and check for errors, then apply your
filter with pcap_setfilter().<br>
Maybe you want to test your filter with wireshark before (not ether src
xx:xx:xx:xx:xx:xx) I didn&acute;t test it, but i think in pcap_compile() you
will have to<br>
use a filter string something like "!= ether src xx:xx:xx:xx:xx:xx" or
"ether src != xx:xx:xx:xx:xx:xx"<br>

  <div>Thanks Helmut.&nbsp; Could the filter be positioned on the Driver
layer?&nbsp; If could, how to write the filter string and then
pcap_setfilter(...)?<br>

      <div>Hi experts,</div>
      <div>&nbsp; There is a problem about use pcap_next_ex(...) to receive
packet in Windows XP SP3.&nbsp; This function will be unexpected to receive
the packet sent by the function pcap_sendpacket(...) in the same port.&nbsp;
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".&nbsp; How could I implement the functionality that the
pcap_next_ex(...)&nbsp;don't receive packet sent by pcap_sendpacket?&nbsp;&nbsp;Any
help from you will be highly appreciated.&nbsp; Thanks!</div>
      <div>&nbsp;</div>
      <div>BR.</div>
