[Winpcap-users] can not get any captured package when

[Lin George]

Thanks Bryan,
Great reply! I have two more comments after experiements,
1.
I have tried your method, but does not work.
I. I ping www.google.com, and get its IP address, say a.b.c.d;
II. then I use WinDump host a.b.c.d, but no traffic.
When I do not use any filter, there is traffic captured by Windump and printed to console.
Any ideas?
2.
In the traffic captured by WinDump, I noticed all the traffic is from my computer to my Lab proxy server (not to the actual web server URL, e.g. www.google.com), I am wondering could the proxy the cause of this issue?
regards,
George
