Unable to capture Windows bridged interface traffic
I can't capture traffic on a bridge created in Windows. I can see traffic in the little graph in Wireshark and it's definitely seeing the interface, but I get an error when I try to start a capture, even as Administrator.
DiagReport-20210105-225830.txt
PacketSetHwFilter() failed.
(Note: libpcap 1.10 should, in this situation, report the error code, which might help figure out what the issue is.)
Does this issue persist in Npcap 1.70? As @guyharris noted, libpcap 1.10 (included in Npcap 1.20 and later) provides better error reporting for this function, and Npcap 1.70 is more careful about which hardware filters are attempted.
If this error ("failed to set hardware filter...") no longer occurs, please close this issue. Problems with actually capturing traffic on a Windows network bridge should be reported at issue #115.
