I was asked to setup a wifi access for the clients who come in meetings with people of our company. But we don't want to give them access to the files on the network, only to internet. I know it's possible because there is so much wifi access everywhere, and we shouldn't have access to the files of these network (macdonalds, airports wifi, ...)
They shouldn't be able to access the files on the computers in our domain, but our NAS don't have windows security, it's linux in them so we have to give public access.
So I'd like some link on how to configure things like that. Do I have to buy some specific hardware? I'm pretty sure I could find that on google, but I have no idea how to ask the question.
