This is a perfect example of why most people should not run their own hardware. Don't get me wrong its really fun to build and configure your own server and I openly encourage people to learn but I also remind them that its extremely difficult (for a novice) to do securely.
Additionally connecting a misconfigured server to the internet doesn't just hurt the server owner but the entire network is affected, as you are providing another piece of hardware that malicious actors can use to execute their attacks.
