We just bought a machine to serve as our in-house production server. For security reasons, we don't want this machine connected to the internet. However, we do have an intranet with a wiki and all the workstations in the office need to be able to get to pages on our intranet. I don't see how this could easily be done because if the server is connected to the router, it will automatically be on the internet (as far as I understand), and if the server is not connected to the router, I don't know how the other workstations would be able to see it.
For all I know, maybe the idea of letting all our workstations (which are connected to the internet) connect to the server defeats the purpose of having the server not be on the internet.
My question is: Is it just as bad to have our server connected to a machine that's connected to the internet as it would be to have the server connected to the internet itself? If not, is there an easy way to allow all our office's workstations to connect to the server?
