Have an edge router "outside" of the PIX, and a TFTP server "inside" the PIX, but when I TFTP the running config from the edge router to the server, the file shows up for a few seconds and then goes to a size of zero. I can TFTP from devices inside the network fine. I can also TFTP from the edge router to PumpKin on my own PC on the inside PC.
It seems the Fedora server is asking for something that PumpKin isn't, and PIX doesn't like it.
Any thoughts/suggestions?
