LPC1768 lwip_tcpecho_sa

I am trying to execute the lwip_tcpecho_sa example for LPC1768 provided by nxp. I am able to build the program successfully and am also able to ping the board. But when I try to send some pakcets using PacketSender or any other tool it is not working as expected. The data is not being received nor echo backed ? What could be the issue ?
