So, I am facing an issue. I run a huge Minecraft server and just recently I got attacked by someone or some IP. My server just crashed instantly and when I invested further in the matter, in the server file log I observed an IP which was something like: 87.175.294.187 > port changed and after that, I got like 20 messages/data packets a second from one IP than it stopped. Now, this is happening with me since the last 3 days, IPs are different and the port changes as well. What's the solution? Someone told me that use a VPN for this, but would it be effective?
