Lately I noticed some unusual traffic behavior coming from my freebsd server that is running ioquake3 (a public ioquake3 server). I shut it down a couple of days ago with the intention of looking at it later in more details to have an idea of what was going on.

I started looking at it today and just found out about this :

I will have to update my firewall in order for me to restart my ioquake3 server. Seems like there is a massive DDOS attack running at the moment using the ioquake3 servers on the internet. I can see some ips trying to communicate with my server, even if it's down.
