Ok, this is weird. Keep in mind that I've set up many 501's and have never had anything like this happen. All I'm trying to do is use a tftp server to uprade to version 6.3 and pdm 3.0. I have the pix directly connected via a crossover cable. I can ping the pix from the pc, but I cannot ping the pc from the pix. Cisco TAC hasn't been helpful to this point. They replaced the pix with a different one and that one didn't even boot up. It turned out to be a bad power supply. They sent me a replacement for the power supply and the new pix booted up fine. However, the same problem on that one. It's very strange that I cannot get a ping response on the firewall when pinging the pc. I tried it using the outside interface as well.
Any suggestions?
