[Winpcap-users] Sniff TCP packets, manipulate their data and send them to another PC

[ceo at triplebit.com]

Hi all,
I'd like to sniff the interface card, save some tcp packets, manipulate 
their data and send the data in a second connection that I opened to a 
second PC.
Is that possible with Winpcap?

If positive , is there some example of code that is close to what I need?

Is there some tool that already does that?

Thanks in advance
