Unblocking port 80 for HTTP traffic in the Fedora firewall

This post describes how you can unblock port 80 to allow HTTP traffic through in the Fedora firewall.

Unblocking port 80 so HTTP traffic can reach a webserver

By default Fedora 27 has a firewall which blocks traffic reaching port 80.

To disable this permanently and reload the firewall configuration so it’s immediately available you can run the following command.

sudo firewall-cmd --zone=public --permanent --add-service=http
sudo systemctl restart firewalld.service

This adds an exception for the HTTP service and unblocks port 80 on a permanent basis.

Hopefully this helps ensure your webserver is accessible from the outside world.
