Iptables configuration file/etc/sysconfig/iptables does not exist

Iptables configuration file/etc/sysconfig/iptables does not exist what to do

The first thing to look at is whether Iptables is installed, using service iptables status or Yum info iptables to see the current status

If it is already installed, run the following command:

Iptables-a input-p TCP--dport 22-j ACCEPT

Service Iptables Save

This will prompt you

iptables:saving firewall rules to/etc/sysconfig/iptables:[OK]

So there will be Iptables's initial configuration file.
