Q.  How can I configure my firewall when logged in thru a terminal window?

A.  The service is called iptables -- not firewall or anything similar.
Fedora 22 and later, this is different.

CONFIGURE

You can modify file /etc/sysconfig/iptables and do

systemctl restart iptables

Or use the text-based GUI:

system-config-firewall-tui

Install that via:

yum install system-config-firewall-tui


ENABLE

If you want it to start when the machine boots:

systemctl enable iptables


LIST

To see the current rules:

iptables -L
