iptables: No config file.


How do I add a iptables config file to Centos 6.8? Thanks

Code:
[Michael@vps2 ~]$ sudo /etc/init.d/iptables status
Table: mangle
Chain PREROUTING (policy ACCEPT)
num  target     prot opt source               destination

Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

Chain POSTROUTING (policy ACCEPT)
num  target     prot opt source               destination

Table: filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

[Michael@vps2 ~]$ sudo /etc/init.d/iptables start
iptables: No config file.                                  [WARNING]
[Michael@vps2 ~]$ sudo cat /etc/sysconfig/iptables
cat: /etc/sysconfig/iptables: No such file or directory
[Michael@vps2 ~]$

It is default for iptables to be empty in CentOS 6. Instead you should add yours rules to iptables and then do a "service iptables save" to save the configuration to file. That would be the recommended way to create any such file.

This is the default, so that if you install iptables remotely, you don't instantly blackhole yourself out the server. As you could imagine that would be rather problematic.
