I think I'd be wary about letting anything outside my firewall do tftp: 
it's not a particulaly secure protocol. Certainly be sure that you're 
not making available stuff which you don't want to be public.

The functionality you want isn't currently there: the code just uses 
ephemeral ports allocated by the OS. It's a good idea, and simple to do, 
so I've implemented it.

adds a --tftp-port-range oprion.


Cheers,

Simon.
