Mohammed originally posted this question in the WAN Routing and Switching forum. I provided some answers and we had some following posts to clarify some aspects of the problem. I came to the conclusion that the real problem is that the FWSM supports TFTP of the image to flash but does not support TFTP from flash. Then Mohammed posted the same question here. I still believe that the issue is that it is not supported to TFTP from flash. If anyone can offer any reference to show that it is supported then Mohammed and I would appreciate it. Otherwise I think that my theory is correct.
