I have a PIX506E that has version 6.3 and I want to upgrade to version 7.21. I got all the bin file and enter the monitor mode. However, for some reason, no matter what I do, my PIX will not get the files from my TFTP server. My PIX can ping the TFTP server but my TFTP server cannot ping my PIX. TFTP server's logs show that ACK blocked. Then I tried to change IP, computers, switch, different TFTP software, and ensure all ports on my computer is open, etc. I just cannot understand why my PIX cannot get the file from the TFTP server. Please help.
