I was sharing a couple things I had made to my friends, via posting it on a forum, and it seems some extremely stupid people find it entertaining to ping\DDOS(or whatever people call it now) my servers\me. I was running a webserver(Apache), mySql server, IRC server (UnrealIRCD) and a Flash Media Interactive Server, and while I was at school today I wanted to show my friends something i had made when I noticed I couldn't connect to my website, well I could but it was loading at an extremely slow speed. So now I'm at home and I completely removed my port-forwards, and shutdown my server. Although I am still experiencing a slow connection to the internet. What steps should I take and how can I protect myself a little more?
