No worries - I thought the diag wasn't clear enough or something . .

Right - that is how I had it previously before the re-arrangement and 
the printer did indeed work with no problems but I still couldn't ssh 
from the netbook to the server even though everything was on the 
192.168.0 range of IP addresses.  In the messing around I was resetting 
factory configurations - so it was less hassle to leave them as defaults.

Yep but that means all the dynamic addresses will be on the 10.1.1 range 
as well?

Right.

Yep.
