I'm thinking of setting up a local server on an old machine I have lying around. So that I can easily ssh into it, I would like to add it to my current network by plugging it right into my router. Currently, all my other devices access the Internet via this router, but I would like to restrict this in my server's case.
Is this something that I can set up right in the router? Or is it operating system specific (I should mention I will be virtualizing my server so it can live beside other VMs, all of them Linux)?
