7.12.3 Set Up a Firewall Rule

The firewall blocks traffic from the WAN zone to the DMZ zone by default so you
need to create a firewall rule to allow the public to send HTTP traffic to IP address
1.1.1.1 in order to access the HTTP server. If a domain name is registered for IP
address 1.1.1.1, users can just go to the domain name to access the web server.
