Resolved GET/POST - Flood (DDoS)

[omexlu]

Hello,

This is not really Plesk related but i need some input to solve that.

I have the problem that somebody Floods my community (protected by cloudflare) but because the zombie PCs don't come from one single IP my fail2ban configuration can not handle that.

So if few thousend zombie come with one GET my community is overloaded and results in a cloudflare 522 ERROR.

Because cloudflare thinks that they are real visitors nothing get challanged.

Now i want to ask the profis here what can i do to prevent that a little bit?

Thanks in advance.

PS. I can challage all "bad" countys in cloudflare but this is very suboptimal...

Hi omexlu,

when you state

This is not really Plesk related but i need some input to solve that.

... WHY don't you open your thread at

=> Home > Forum > General Discussion > Open Topics

... as suggested many, many times here in the forum, when the thread isn't Plesk - related ?

Maybe someone from the team can move it there in place

But i really need a solution for that problem
