[Windump] windump usage question

[qwer 1304]

Hi,

I'm having a problem with a remote server that seems to misbehave and wanted to use windump/tcpreplay to debug the issue.
I captured a session with the server using windump and now I'm sending them out to the server using tcpreplay.

However, I need to capture responses from the server to the packets sent out with tcpreplay.
I thought I'd run windump (in one window) and then send packets out with tcpreplay (from another window) and capture server responses in windump.

I tried that, but windump didn't capture anything (it also didn't capture the packets sent out by tcpreplay). It did however captured packets that were sent to the server with a browser and the server responses (so windump works and the parameters are OK).

Question:
Is this setup possible? If so - why don't I see any packets captured by
windump? If no - could you recommend a setup that would work?


Thx,
David
