Alternatively, you use (say) a Linux box as a router between two 
ethernet networks, one of which has the DHCP server.

Thinking about it, IIRC the client uses a different socket to the 
server - so is it possible to just filter inbound packets from a 
client on the DHCP Server facing interface so it can receive the 
traffic from the server but ignores clients ?

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon 
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the disk and re-install the 
printer OS on it. If anyone knows where I might get hold of one I'd 
be grateful - requests to Canon drew a blank, it's been out of 
support for years.
Alternatively, if anyone has one of these and would let me image 
their hard disk ...
