online web application to CC3200 Communication

I need to access CC3200 wifi based device over the internet, How it is possible , what are middle devices required ?

For example :

-> At home CC3200 wifi device connected to Home Wifi Route.

-> Home Wifi Route having Internet access.

-> In office there is another Route connected to internet

-> In office Laptop is connected to Office route.

Now should I access "CC3200 wifi device" from "office Laptop", can I ping it or it need other cloud web server as middle translator ?
