The remote subnets (but not any others) should all be within one 
shared network like this :
shared-network "some-name" {
   subnet 192.168.0.128 ...
   subnet 10.250.0.200 ...
   subnet 10.250.0.208 ...
   subnet 10.250.0.224 ...
}
subnet 192.168.0.0 ...
}

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.
This is NOT the same thing as the printer drivers to load on the 
computer - there's no problem there.
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 ...
