So the case is that I got DDOSed and i scanned my internet traffic with wireshark where i found a pattern in the IPs attacking me and now i have a list of 14228 IPs that i would like to block from accessing me. How do i do that?
 
Solution
At the consumer level, there is only one way to ward of a DDOS attack:

Don't antagonize an idiot who might go to those lengths to harass you.
You can't really. Your router just because it is running NAT and NAT is stupid it protects you. Since it does not know which machine to send data to when it comes in from a unknown host in the internet it just drops the data. That is what you want to do anyway.

Even if you could put in that many ip the data would still come to your router. It would just be dropped by the rules rather than the NAT. It still does not solve the problem of all the incoming sessions the damage is done way before your router even sees the data.

'Blocking' IP addresses on a single router actually doesnt stop a DOS attack. If it did, they would be easy to stop. The router still has to look at the packet find the IP address, and then drop it. Thus its still having to deal with it.

This is just a script kiddie who DDoSes everyone he wants in one CS server... If anyone wants to give him a lesson IP address redacted by Moderator that is his IP
