How to create new reply packet in tcp communication with NDIS filter?

Question

Hi,

I try to implement following scenario with NDIS filter.

In TCP communication, I try to capture outbound http packet and create redirect packet to response. e.g. after TCP connection is established, when I capture http packet with GET method, I create 302 http packet, then reply it.

In my test, I test the function with IE, and I found : wireshark has captured my packet(302 redirector), and every field(SEQ, ACK,checksum) is OK, but IE does not receive the redirector packet, it is waiting for long time.

I don't know what happened, please help me.

Thanks,

Rick Wang

Hi,

If you connect it with wifi, you can try going to Show all connections->right clicked on my LA connection->properties->Internet Protocol (TCP/IP) Properties
and selected the checkbox Obtain IP address automatically.

And you can refer the similar thread

And I think you can post the thread to tcp forum where you can get better answers.

Hope it can help you.
