Hi everyone in the Cloudflare community!
I’ve just joined Cloudflare to solve my problem with SYN-flooding, setting my webserver under pressure for several days by now. My own attempts to mitigate it with iptables rules helped only for some time and I decided to use Clouflare for help.
My server is on a separate hosting and I changed NS names to Cloudflare ones, so that my domain resolves by Cloudflare. The issues with SYN-flooding remain.
Maybe this question sounds stupid, but how does Cloudflare help with attack mitigation, if packets go to a particular IP address? The server is still on the same IP and whatever DNS changes I do, it will remain there.
