[Techtalk] nat firewall and tftpboot

[Maria McKinley]

I am having a very hard time getting my diskless servers to boot off the 
network. It use to work, but unfortunately, a bunch of things have 
changed, and it was impossible to change things one at a time, so I 
don't know where the problem lies. (All IPs changed, the firewall 
changed, the DHCP server changed, and I'm now using NAT, where I wasn't 
before.) I am looking for a good tutorial or how-to on setting up a 
tftpboot server, which at least mentions doing this on a network where 
there is one-to-one NAT. Anyone know of one? I've tried googling, but 
mostly get stuff for macs and bsd. I'm using debian (although anything 
based on linux would be helpful).

thanks,
maria

In case someone is an expert:

Using ethereal, I see that the client starts to receive the kernel 
packages, but after a large chunk, the tftp server requests repeatedly 
to know who has the client's ip, but the client does not appear to 
answer, and then the client boot fails with the message "Too many packages"
