Only allow user specific resources?

[oguruma]

I need to grant access to a share on my network via VPN. I have an existing OpenVPN server for the members of my household.

The issue is that all I want is for the user in question is to be able to access is the specific (FreeNAS SMB) share. I don't want them to be able to access any other network resources, nor do I want the rest of their internet traffic going across my NICs.

Is there a way to accomplish this in the PfSense OpenVPN server?
