    Hi

    I am thinking to limit user connections on server per ip in case that someone run a siege benchmark on my server and maybe try to kill it (too many connections) or in general try to use many connections from a single ip but i am not sure which is the best way to do it ?

    Nginx level or Csf level?

    Nginx level will react faster as it will block or add it at wait stage but csf after a minute if the site is up :) will block the ip.....

    And what number to use for for a forum about?

    Thanks :)

    If i want to change the limit to 50 connections on :

    limit_conn limit_per_ip 50;

    do i have to change also this 16 value to 50?

    limit_conn_zone $binary_remote_addr zone=limit_per_ip:16m;
