To make a local web server public:
1.
Assign your web server either a fixed IP address or a dynamic IP address using DHCP
address reservation.
In this example, your router always gives your web server an IP address of
192.168.1.33.
2.
On the Port Forwarding / Port Triggering page, configure the router to forward the
HTTP service to the local address of your web server at 192.168.1.33.
HTTP (port 80) is the standard protocol for web servers.
3.
(Optional) Register a host name with a Dynamic DNS service, and specify that name
on the Dynamic DNS page of the router.
Dynamic DNS makes it much easier to access a server from the Internet because you
can enter the name in the web browser. Otherwise, you must know the IP address
that the ISP assigned, which typically changes.
How the router implements the port forwarding rule
The following sequence shows the effects of a port forwarding rule in which your router
always gives your web server an IP address of 192.168.1.33:
1. When you enter the URL www.example.com in your browser, the browser sends a
web page request message with the following destination information:
•
Destination address: The IP address of www.example.com, which is the address
of your router.
•
Destination port number: 80, which is the standard port number for a web
server process.
2.
The router receives the message and finds your port forwarding rule for incoming
port 80 traffic.
3. The router changes the destination IP address in the message to 192.168.1.33 and
sends the message to that computer.
4. Your web server at IP address 192.168.1.33 receives the request and sends a reply
message to your router.
5.
Your router performs Network Address Translation (NAT) on the source IP address
and sends the reply through the Internet to the computer or mobile device that sent
the web page request.
