hi,
i wrote a client/server code and i'm sure the code is 100% correct ,but i can receive packets in both side.
The problem may be due to the firewall or network configuration error or such,but i can't really know what is the it.
How can i troubleshoot the problem??
P.S:I connected two PCs using cross-over UTP and set the IPs and subnet mask correctly.

Please re-phase your question. I don't read where the problem is other than your 100% code maybe flawed..
debug the network with ping (ICMP), netcat send/listen modes (TCP/UDP), check traffic with wireshark
check your routing and firewall settings - Windows blocks ping by default
