winpcap giving the problem in sending packet

[ujb]

I am using two network cards on a system.
I am using winpcap to send the packet that I receive from one interface and sending it to the other interface the packet does reach the intended destination but the reply(ping request is reached at the destination but reply does not generate) does not appear.
Please If you can help me in the solution of the problem.
