Nginx Reverse proxy + SYN Flood
- by Bradley
We're running a nginx reverse proxy cluster, forwarding traffic to our main website, this enables us to filter out unwanted traffic/users etc, and send them off else where, now we have a few issues with SYN floods where the requests a second is overflowing the proxy + the main server causing them to become unavailable.
Is there any ip tables magic that can
A) Rate limit SYN packets / connections to HTTP
B) Block it all together if packets a second is malicious
or any advice how to use limit_rate_zone in nginx, I've googled and tried to apply a few new results and none of them work and the websites are still unavailable.
