I’m trying to help a friend setup storage for his office network, sorta like a personal cloud. He’s not interested in using cloud storage because he works with sensitive data. He’s asked me to setup the storage to be accessible via wired connection only. I was thinking I’d set up a NAS for the office and get it setup through the network but I was unsure of how to set it up to be accessible through a wired connection only, so that you cannot connect from wifi. I haven’t bought the equipment so I’m sure once I have it and can play around with it I can figure it out but if anyone could tell me how easy it is or give me any tips I’d really appreciate it.
Instead of jumping through hoops to try to solve for this, the better question is why he doesn’t want it accessible via wifi.
It honestly sounds like he is trying to find a solution to cover up poor network hygiene, and setting up guest network protocols and taking all non-critical devices off of his main network would be a much better solution.
If you find a way to do what he is looking for you to do, I almost guarantee he is going to reach out in a few months and ask you to figure out a way for him to also access that device while traveling or working from home, which would require a convoluted solution like having a second machine at the office that is only used for remote login.
