Hi,
I tried the following and it is working as expected. Thanks.

iptables -F INPUT
iptables -A INPUT -p tcp --dport 3306 -s $'172.29.0.2' -j ACCEPT
iptables -A INPUT -p tcp --dport 3306 -s $'172.29.0.1' -j ACCEPT
iptables -A INPUT -p tcp --dport 3306 -j REJECT
service iptables save

But I have to allow one IP address at a time. It does not accept comma
How do I add multiple IP addresses?
