Openvpn on Rockstor server

[Machoom]

Hello, I'm wondering if someone can help me out by clarifying some confusion I have. I built myself a Nas server running Rockstor which is linux based specifically centos. I was able to install and run openvpn on my server and was able to download and configure the client software on two local pcs and another pc off site. I was under the impression that the openvpn on my server would have gave me access to shares on my server on my off site pc, but I'm thinking that's not the purpose of the vpn server. What am I not seeing? The pcs all connected fine and connection was successful. Is my data just being encrypted through the vpn to my server? I'm new to all of this and just wanted some clarification. TIA
