IPtables maximum recored added
I want to block a range of IP's from some countries to connect to my server and I will edit this file /etc/sysconfig/iptables
the list of range is aboute 11000 range of IP's .
what is the maximum no of IP range that could be added to /etc/sysconfig/iptables ?
is it will slow my server if adding that huge range to IPtable ?
