lan packet sniffing

Sir,

i have one computer inside my lan (192.168.1.3)

The PC will connect to the public server using tcp connection
(tcp www.abc.com port 32000)

The public server will send certain info to my pc once connection establish.

Is it possible for me to sniff incoming packets from server www.abc.com to my pc 192.168.1.3. After i sniff i need to generate same packet from my pc with spoof ip www.abc.com. If i do that i no need to use internet.

I need to do testing on that, can anyone share with me what software to use and how to do it.

Thanks
