[Winpcap-users] mirroring Ethernet frames

[Seifert Johannes]

Hi Sam,

thanks for your answer! I've searched the Documentation for this feature and I found the keywords "inbound and outbound". It seems that these keywords do exactly what I need.
But if I define a filter like "inbound and proto 0x88A4" it doesn't work and I have no idea why.

Thanks,
Johannes

You need to use capture filters to achieve this. Take a look at the
documentation regarding "filters".

Hi,

I've searched the internet for help but I didn't found a solution for
following problem: I've written a small program which simply mirrors the
received Ethernet frame, if the frame  hast a defined EtherTyp. That
means that the received frame is directly send after receiving. 
The problem is that the send telegram is interpreted as a received
telegram. Also it is possible that same frames are received from
"outside". That makes the solution with a buffer impossible.

My aim is that only the telegram's, which come from "outside", are
mirrored.

Thanks,
Johannes

Ps: sorry my English isn't the best.
