I'm no network guru, but I doubt there's any way to prevent network connectivity via the router. In windows you would set your connection as public. That would prevent your computer from being seen via typical means.

using an additional router, which can be configured, how you want it

DD-WRT can be helpful too, if your router is supporting it.

Not sure if I fully understand your question, but you can have a look at this:

You can switch off file sharing etc so others cant see your files on the network. But if you connect to a domain the the domain admins can generally override this. If you dont connect to a domain the windows firewall also helps prevent unwanted connections to your computer from the LAN and from the internet.

What size network are we talking about? Is this a home or business network? What it sounds like to me is that you need a managed switch with VLANs. You could setup the "one PC" so that it can get to the router but to no other devices.
