RHEL 7 / CentOS 7 : Disable Firewalld and use iptables

Hello,

Just installed CentOS 7 on my Virtual machine and realized that, Firewalld is bit complicated as I am using iptables firewall from many years. So decided not to use firewalld at least as of now and wanted to continue with iptables commands as I was using in RHEL / CentOS 5 and 6.

I thought iptables will not be there and I will have to deal with firewalld but a little small trick in RHEL7 takes me to the solution which I wanted and I found that I can still use the iptables by disabling firewalld service.

So, If you are in same condition as mine and you want to use iptables on CentOS / RHEL 7 instead of firewalld, Please follow this howto.

As we all know that, CentOS / RHEL 7 both are completely systemd based, So We will have to use few systemd related commands to disable firewalld and enable iptables service.

1. Disable Firewalld Service.

2. Stop Firewalld Service.

3. Install iptables service related packages.

4. Make sure service starts at boot:

# If you do not want ip6tables, You can skip following command.

5. Now, Finally Let’s start the iptables services.

# If you do not want ip6tables, You can skip following command.

Firewalld Service is now disabled and stop, You can use iptables.

Now, You will be able to use iptables as your firewall, You can add / remove rules as you were doing in previous releases of Red Hat / CentOS 5 and 6, You can configure firewall with iptables in same manner as previous.
