FirewallD is the frontend management solution of iptables for most of the Linux distributions. It provides an easy-to-use command line and GUI-based interface to manage iptable rules. This tutorial describes to you to open port 80 (HTTP) and port 443 (HTTPS) in FirewallD.

Allow Port 80 & 443 in FirewallD

Using firewalld, you can allow/deny any port temporarily or permanently. The temporary allow/deny rules will be removed after the system reboot. But the permanent rules will persist even after the system restart.

The following commands allow incoming traffic on TCP ports 80 and 443 in firewalld.

sudo firewall-cmd --zone=public --add-port=80/tcp 
sudo firewall-cmd --zone=public --add-port=443/tcp 

The --permanent option insures to remain firewall rules after system reboots.

sudo firewall-cmd --permanent --zone=public --add-port=80/tcp 
sudo firewall-cmd --permanent --zone=public --add-port=443/tcp
