VPN Setup

Hi

I have a server at home running server 2012 inside that i have a domain controller running server 2012 r2 as a virtual machine on hyper v
on my domain controller i have several movies on it. i was thinking off setting up a vpn on this so my friend can access and watch the movies

How can i setup a vpn so he can do this, or is there any other way this can be possible

Thanks
