7.10.2 Configure NAT

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.
