I lease server space for the website I create from a major company, but I would like to have a basic Linux and possibly a basic Windows box at home that I can use for testing databases, an in-house FTP servers and a server that I can install scripts which need root access to install.
I have a couple of desktop computers that I can sacrifice for the project. I have a 5meg cable connection at the house, but at this point it is a dynamic IP.
What do I need to do to use that connection as a server (it is cableone if that matters), and keep my existing in-house network secure (wired and wireless)? What OS versions should I use, and how do I configure my network to configure the IP's appropriately?
