19.2.2 Tutorial - How to Allow Public Access to a Server
This is an example of making an HTTP (web) server in the DMZ zone accessible from the Internet
(the WAN zone). You will use a public IP address of 1.1.1.2 on the ge2 (or wan1 on some models)
interface and map it to the HTTP server’s private IP address of 192.168.3.7.

Public Server Example Network Topology
Follow the following steps for the setting.
1
Configure Address object
Create two address objects. One is named DMZ_HTTP for the HTTP server’s private IP address of
192.168.3.7. The other one is named ge2_HTTP for the ge2 (wan1) public IP address of 1.1.1.2.
2
Configure NAT
You need a NAT rule to send HTTP traffic coming to IP address 1.1.1.2 on ge2 (wan1) to the HTTP
server’s private IP address of 192.168.3.7. Use the following settings:
• This NAT rule is for any HTTP traffic coming in on ge2 (wan1) to IP address 1.1.1.2.
• The NAT rule sends this traffic to the HTTP server’s private IP address of 192.168.3.7 (defined
in 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”.
3
Configure secure policy rule
Create a firewall rule to allow HTTP traffic from the WAN zone to the DMZ web server.
Now the public can go to IP address 1.1.1.2 to access the HTTP server.
