The controller should be reachable by the switches so that the openflow channel can be established between each of them and the controller. You shouldn't be able to ping between hosts if the switches haven't connect to a controller that runs a forwarding algorithm. What kind of switches are you using? And what command are you using to start NOX (do you start any forwarding components like e.g. pyswitch ) ?
