Scenario / Questions

In CentOS 6 I could type setup from the command line and I would be presented with a set of tools, one of them being Firewall configuration. I can still do this in CentOS 7, except the list no longer includes Firewall configuration as an option.

Does anyone know where I can find it now and why it has been moved?

This is where I used to go to allow incoming traffic via HTTP and HTTPS. If there’s a better way, I’d gladly take the advice. Thanks.

Since the release of RedHat/CentOS 7, the previous firewall system has been replaced with firewalld.

At the time of writing there is no curses-like console interface similar to system-config-firewall. If you don’t mind using a GUI you could use firewall-config instead.

If you need something for the console you will have to use firewall-cmd instead.

I hope this might help you!

Here are some commands with descriptions below that I came across and were helpful

firewall-cmd --state
  view status of firewalld service (systemctl status firewalld)
firewall-cmd --zone=public --list-all
  gets all info for the “public” zone
firewall-cmd --list-all-zones
  shows all info for all zones
firewall-cmd --zone=public --add-port=80/tcp --permanent
  adds port 80 to public zone
firewall-cmd --zone=public --add-service=http --permanent
  adds service http to public zone
firewall-cmd --reload
  run this after making changes
firewall-cmd --zone=public --remove-port=80/tcp --permanent
  to remove port 80 from public zone
firewall-cmd --get-default-zone
  shows default zone for firewall
firewall-cmd --get-active-zones
  zones where network interfaces or sources are assigned

A quicker way of disabling firewalld is the following.

 systemctl disable firewalld

this removes the .service so you should get something similar to

rm '/etc/systemd/system/'
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
