Say you have a computer on IP 132.132.132.6 with subnet mask 255.255.255.0
and gateway 132.132.132.254

You want to setup your new network printer with a private IP. The printer
gets a private IP of 10.78.22.130. What do you put into the printer for a
subnet mask? Do you put 255.255.255.0? What would you put for the gateway
on the printer since it is a private IP but you want it to communicate with
your public IP computer?
