File Sharing with firewall on Sever 2012 r2

Hi,

I'm new to the hole Windows Server 2012 thing but currently I'm trying to configure my server in the correct way.

It's a file server and I connect via VPN to it. Now I'm fighting with some firewall settings. My goal is, that i can access shared folders only through the local IP address. I set the Ip range of the VPN from 10.10.10.1 to 10.10.10.255.

Although i disabled file sharing for all network profiles, i can still access over the local Ip of the server (10.10.10.1). Why is this possbile?

A second thing what I'm trying to figure out is: How can i configure the firewall, that i can not open a shared folder through the public ip adress of the server. Even if i set the remote adress for the firewall rules to local subnet, i can still access through the public ip when I'm connected to VPN.
