Use Configuration > Object > Address > Add to create the address objects. 

Create a host address object named DMZ_HTTP for the HTTP server’s private IP 
address of 192.168.3.7. 

Figure 101   Creating the Address Object for the HTTP Server’s Private IP Address 

Create a host address object named Public_HTTP_Server_IP for thepublic WAN IP 
address 1.1.1.1. 

Figure 102   Creating the Address Object for thePublic IP Address   

You need a NAT rule to send HTTP traffic coming to IP address 1.1.1.1 on wan1 to 
the HTTP server’s private IP address of 192.168.3.7. In the Configuration > 
Network > NAT screen, click the Add icon and create a new NAT entry as 
follows. 

• Set  the  Incoming Interface to  wan1.
• Set  the  Original IP to the Public_HTTP_Server_IP object and the Mapped 

IP to the DMZ_HTTP object.

• HTTP traffic and the HTTP server in this example both use TCP port 80. So you 

set the Port Mapping Type to Port, the Protocol Type to TCP, and the 

original and mapped ports to 80.
