How do you precisely set CONNLIMIT & PORTFLOOD for the port 80?

Hello,

most un-optimized site with most elements (images, css, js..) i host has approx. 110 elements and it takes around 18 HTTP connections per second on slower internet and slower PC.

Here i parsed HTTP access log for that site: http://pastebin.com/ycn3m1si

It is nice to see how HTTP connections are spread over the time.

Is this all you need to know in order to set firewalls connection limiting per IP?

Without optimizing, how should i set config server firewall CONNLIMIT (max. IP connections per the port and time interval) & PORTFLOOD (maximum concurrent new/SYN connecton of an IP) so i do not ban this site visitor who browse this website actively?

CSF readme where these variables are explained: http://download.configserver.com/csf/readme.txt

From my point of view i know how to set PORTFLOOD. I would set like 25 concurrent connection per IP when i got 18 concurrent. But is it enough? Why not?

Sligtly more difficult is for me to set the limit per time interval

Thank You
