@Nightw0lf You are network engineer or what? By reading your latest posts i assume that you don't have a clue about a ddos attack. How the hell you try to advise people here?
Here is what going on with DDoS attacks:
Let's clear on fact, if you will be attacked by a proffesional, you have no luck for sure. You will be down 100%.
Let's go now on the fact about what you can do in order to prevent the smartasses with the stresses who want to attack your server because they want to be pimps when they will grow up.
The only solution for random server owners is that you will rent a good dedicated on a good hosting company. I recommend hyperfilter or stormwall (both tested and guaranteed that you will be fine for basic ddos attacks).
OVH is good too, BUT only if you are smart enough to setup a basic firewall on a linux-dedi server first. There are ovh ddos scripts who bypass their mitigation filters for fun.
Extra Advise: Stop using vps servers as proxies in order to have "extra security", this cannot happen. The only thing that you can achieve with those proxies is to help the attackers to shutdown you faster. 100mbps nic? cmon! Its about 50usd on a simple stresser!
The only way to stop a professional ddos attack is to have many PoPs around the world with 10Gbp/s NIC cards and a mitigation device before your endpoint server. So simply, you need bandwidth.
PS: Of course there are some extra tips/systems which i saw sometimes used by people and they successfully prevented the ddos attacks on their servers, but this is a story for another day!
