plz plz plz plzhelp me(its urgent)

I am using the winpcap library to send the arp and icmp echo packets. I am setting the appropraite attributes for the packets. The packets do reach their destination but the reply like icmp echo reply and rarp packet are not generated form the destination,
plz if you can help me or refer any website of winpcap telling me the proper attributes for sending or detect the problem or can send me any code.:confused:

If the other peer is receiving the packets, then we have two possibilities:

- The other peer is not sending a response, firewalls tend to ignore incoming ICMP packets.

- You are not receiving the packets because you could be retrieving them wrong from the buffer.

Are you trying to do ARP to a puter in another network? (aka trying to route ARP, big mistake).
