Date: 2012oct3 OS: Linux Distro: pre Fedora22 Warning: Basically obsolete info. Use firewalld if available. 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 dosystemctl restart iptablesOr use the text-based GUI:system-config-firewall-tuiInstall that via:yum install system-config-firewall-tuiENABLE If you want it to start when the machine boots:systemctl enable iptablesLIST To see the current rules:iptables -L
