Fix: Firewall is stopped (iptables) in linux

I came across this quick fix when trying to restart the firewall for my linux box.

$ service iptables status
Firewall is stopped.

Trying to start it?

The obvious solution was to just do service iptables start but this didnt do anything.

Solution

We just need to save the firewall rules before we start the service.

$ service iptables save
Flushing firewall rules:  [  OK  ]
Setting chains to policy ACCEPT: filter [ OK  ]
Unloading iptables modules: [  OK  ]

$ service iptables start
Applying iptables firewall rules: [  OK  ]
