I'm trying to use winpcap to build a software bridge using two lan cards -- but seem to be in an infinite feedback loop. I open both NIC's using pcap_open( "rpcap://theDeviceName1", ... ) and "rpcap::/theDeviceName2". Then I start two threads, each collecting frames on one of the NIC's using pcap_next_ex(). Immediately after reading a frame, the reading thread sends the frame out untouched to the other NIC using pcap_sendpacket(). Unfortunately, as soon as I send a frame on a NIC, it's immediately read back in and sent out the other NIC (where it's immediately read back in and sent back out the original NIC). The frame ping-pong's back and forth forever generating LOTS of network traffic!
Is there any way to prevent the pcap_next_ex() function from reading back in a frame just sent with pcap_sendpacket()?
