As a note: I have read through Mugem's guide, and I think it is a great starting point, but there are a few things that I don't like that I am going to touch on here.
READ CAREFULLY AND THOROUGHLY.
1. Stop trying to change your IP.
Guys, if someone wants your IP, they are getting it. Fuck, if you post on this forum once, your IP can be obtained. If you stream, play WoW, go on Skype, watch a stream, someone can get your IP. It isn't really something that is SUPPOSED to be secret. You need to thwart DDoSing at the heart of the issue, which I will explain in the next header.
2. Basics on DDoS.
A basic DDoS attack, which you guys already know, is pretty much connection flooding on some port(s) on some IP(s). It is really very easy to stop this.
- Buffer the amount of connection requests and responses in a short period of time.
- Prevent that traffic from even making a request.
3. Buy a router made in the last 5 years, and actually take time to set it up.
Routers don't want to deal with the kind of flooding that is DDoS. They stop it. They manage it. Turn on the router's firewall, don't forward ports you don't have a reason for forwarding. Enable IPv4 and IPv6 SPI firewall protection, if it isn't already.
4. Get a free firewall, and prevent incoming traffic from EVERYTHING. Then enable it where needed.
Do that ^.
5. Skype Shit
For the love of fuck, turn off:
"Use port 80 and 443 as alternatives for incoming connections".
Port 80 is the HTTP port, and that is the first port ANYONE is going to try DDoSing you on.
Disabling it won't negatively affect ANYTHING.
Set-up a Skype proxy. Mugem's guide has good resources for doing so. Pick a high rated proxy in your region with a low MS, and you can screen share with the same quality as not having the proxy.
That's really it guys. A basic DDoS is easily preventable through controlling traffic, and not making yourself vulnerable. If you are having problems beyond that, you really need to contact the appropriate authority for your nation. It isn't a bunch of nerds on WoW, it is terrorism.
"Denial-of-service attacks are considered violations of the IAB's Internet proper use policy, and also violate the acceptable use policies of virtually all Internet service providers. They also commonly constitute violations of the laws of individual nations."
Was motivated to write this after reading a thread. Probably has typos and grammar errors, but read through it, think about shit, and do some research. Take the time to set up your router, firewall etc. thoroughly. If you don't know what an option does, look it up.
Drunkbaby's post quoted, has good information.
