Can winpkfilter be used to send packet as if it is coming from remote PC ( internet remote host like yahoo ? )

Sure. The easiest way for you to start is take and parse the normally received packet (intercepted from the network). You can do it with one of the network sniffers (like Network Monitor or Ethereal). Then just build your own packet with WinpkFilter on the same way. Of course it requires some understanding of how TCP/IP works..

Thanks for the reply serpertine, I am able to send the packet to local host it self. But its not TCP/IP packet. It becomes LLC packet. I want to send the packet to my PC itself but as if its coming from remote server with IP, TCP and Ether header. Can I do it using winpkfilter ? If yes how can I do that ?

The code above initializes only Ethernet header and sets next protocol as IP without initializing the IP header. This may cause sniffers to show this packet as a bogus one.

Can you please tell me how to set IP header. I tried to create one and send it to my own PC, I am able to sniff it but its not like a typical IP, TCP header packet. Instead it shows as Logical Link Control packet. Can winpkfilter be used to send packet as if it is coming from remote PC ( internet remote host like yahoo ? ) Please please help me out. I am in deep trouble …

Thanks a lot for the code snippet. Am using this with the example of passthru. It works with http requests. But its not working with the IM’s like yahoo/gtalk. Can any one please helpe me out.
