ssh into fedora inside virtual box over internet

I am running fedora server in a virtual box inside a windows 7 host. I can ssh into fedora from this windows 7 host.

How ever, I stay out of my place most of the times with a laptop at my disposal, but its config doesn't allow me to run vms on it.

What I am looking for is ssh-ing into my VM from my laptop over internet.

Is this possible ? if yes, how do I have to configure it ?

I am very new to linux and I need some help.
