Setting up Metasploiable 2 network

I've recently installed Metasploitable 2 and I would like to set up it's network in the following way:
I'm ruing Metasploitable 2 on a VirtualBox on my PC, and what I'd like to do is to be able to communicate with it through Kali Linux which is installed on my laptop (not virtually).

My question is: How do I need to set up the network on VirtualBox for this to work?

Thanks in advance.
