Dear najeeb
#policy for the chains
#iptables --policy INPUT DROP
#iptables --policy OUTPUT DROP
#iptables --policy FORWARD DROP

first all those ips which u want than block them.


allow command
iptables -t nat -I PREROUTING -s 192.168.3.2 -i eth0 -j ACCEPT
iptables -t nat -I PREROUTING -s 192.168.3.3 -i eth0 -j ACCEPT

block all command
iptables -t nat -I PREROUTING -p icmp -s 192.168.3.0/24 -i eth0 -j DROP
