[Winpcap-users] My NIC is redirecting/replicating packets whensniffing

[Gianluca Varenni]

I have no idea. It looks like a bug in the NIC or in its driver (WinPcap does not replicate such packets). Are you using the latest available driver for this NIC?

Have a nice day

  Hello,

  I found that my NIC redirects (or replicates) some traffic when in promiscuous mode. I mean, it sends some packets back to the network: The same packet, except for sending its own MAC address instead of the original one. Found it happens most with SIP, ARP, ICMP, I haven't discarded if it happens with another protocols as well.

  My machine runs Windows Vista Bussiness, my NIC is RTL8101.

  The problem happens with Wireshark, but also with WinDump.

  Suggestions?
