Use Back to My Mac

If you have an iCloud account or MobileMe subscription, you can use Back to My Mac to connect to your other Mac computers over the Internet.

Using Back to My Mac, you can access all of the computers you use with iCloud or MobileMe. You can share files and use Screen Sharing to control the remote computer from anywhere you are connected to the Internet.

Back to My Mac requires a router that supports NAT Port Mapping Protocol (NAT-PMP) or Universal Plug and Play (UPnP) in order to share services.
