PHP Code:



iptables -A INPUT -p tcp --dport 80 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT 
iptables -A INPUT -p tcp --dport 80 -m conntrack --ctstate NEW -m limit --limit 32/sec --limit-burst 32 -j ACCEPT 
iptables -P INPUT DROP

How can I calculate the maximum possible number of new connections? Can I start with the characteristics of the server?

Not sure I understand your question. You are only allowing 32 new connection/sec so the most you can have new is 32 every second.
