Please note that hosting a publicly accessible server in your room at home is specifically prohibited by some employers in heavily regulated industries, and if found, this may result in a large fine (enough to cover the company security re-audit cost) and termination. They even prohibit having a public IP on the router, having IPv6 support, having firmware other than the manufacturer-supplied one, and even having access to the router (i.e., it's the manufacturer and the ISP who should be responsible for security updates, for ensuring that there is absolutely no way for attackers to enter the home network by means of routing, and for the fact that you cannot screw that up).
Having a server for your own use from within the home network is fine.
