LTM/ASM DDoS prevention - help
As I'm newbie with F5 LTM with ASM module, would you please help to guide me on some of issues below:
1. Our setup is some Virtua Servers running on HTTP and HTTPS. Within normal conditions, it's working fine without any problem. When we used a special tool to generate HTTP traffic ( only GET cmd) (around 15000 HTTP_REQUEST) within 10 minutes, it ran for around 1000 requests, after that timeout for 10 request and returned to normal. I'm wondering if LTM has any default configuation for prevention such many requests in short time? We tested by generated the traffic directly to Tomcat server (a member of VS's pool) and no timeout with same test. Any idea on this and how to know which caused the timeout?
2. As browsed thru the documentation, I only found how to limit the connections (TCP, UDP) to a VS but not limit the maximum connection from each client to the VS (ex: each clients can only have 100 TCP connections as a time, if the connection exceed, it should be rejected)?
Thank you very much.
