[Winpcap-users] PCAP_OPENFLAG_NOCAPTURE_LOCAL problem

Hi,

I am using to different pcap_t on one network device. One is for receiving packets and the other for outgoing packets.
The pcap_t for receiving is used with PCAP_OPENFLAG_NOCAPTURE_LOCAL as flag for pcap_open.
My problem is that the packets send over the pcap_t for outgoing packets are captured by the pcap_t for receiving packets.

Does PCAP_OPENFLAG_NOCAPTURE_LOCAL only prevents a pcap_t from capturing the packets send out over this particular pcap_t or what is the matter with this?

Thanks,
Markus
