How can I connect to My Book Live from another network?

I have a My Book Live in my homegroup and when I’m connected to the internet from home I can access it without any problem. However, when I’m connected to the internet from my job, I cannot access it. Does anyone know how to fix this? I’m using Windows 8…

WD 2go.

Still couldn’t access it:

However, I wonder if there is some network configuration I can change in order to access it, because through WD 2 GO I’d have to use java…not something I’d like to do unless there is no other way out.
