Hi Guys

This is a reoccuring headache for me. I need to upgrade our Cisco box.
Our setup is of course like this:

Cisco --- Bordermanager --- TFTP server (pumpkin on a windows box).

I've tried two setup's:

1) Made a static nat from a public IP to an internal IP.
unloaded filters
issued a 'copy tftp:tada.bin flash:' on the cisco.
It then tries to connect, but nothing appears on the windows box.

2) Loaded tftpd.nlm
unloaded filters
issued a 'copy tftp:tada flash:' on the cisco.
I tries to connect, a line shows up on the tftpd server, and then the
cisco reports a 'file not found' error.

What do you guys do to upgrade it?
