I have a situation where there are three subnets within a building. Each subnet essentially isolates separate units within this group. In looking at different options for a file server, I am trying to research if it is possible to setup a single file server to support all three subnets. What I am unsure of is how to restrict which directories can be viewed based on which subnet the request is coming from or if it is possible (though, with it being 2013, I expect it probably can). It is a mixed environment with end users having OSX or Windows 7 and the total number of users across all three subnets is less than 250, averaging 130 any given day. There is no established OS baseline for servers, though I am attempting to migrate as much as possible to CentOS as replacement time comes around.
Thank you for your help!
