I am just running the examples, PassThru and PacketSniffer only.
but its not sniffing in the XP-bridge mode.
Well it works OK in test environment and you are the first one who reported problems like this. Could you provide the complete details about it? It would be good if you provide ipconfig output, listadapters output and how do you start passthru sample (with it’s output compared to some other tool which shows you packets). Some broken functionality can be alo caused by installed firewall or some sort of other low level network software.
Also, which version of WinpkFilter are you using?
