5.5.2 Set Up a Firewall Rule
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.
Click Configuration > Firewall > Add. Set the From field as WAN and the To field as DMZ. Set
the Destination to the HTTP server’s DMZ IP address object (DMZ_HTTP). DMZ_HTTP is the
destination because the ZyWALL applies NAT to traffic before applying the firewall rule. Set the
Access field to allow and the Service to HTTP, and click OK.
