Router mode application example: Make a local web server
If you host a web server on your local network, you can use port forwarding to allow
web requests from anyone on the Internet to reach your web server.
To make a local web server public:
1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP
In this example, your access point/router always assigns your web server an IP address
2. On the Port Forwarding / Port Triggering page, configure the access point/router
to forward the HTTP service to the local address of your web server at 192.168.0.33.
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 access point/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.
Router mode: How the access/point router implements a
port forwarding rule
The following sequence shows the effects of a port forwarding rule:
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 access point/router.
•Destination port number. 80, which is the standard port number for a web server
2. The access point/router receives the message and finds your port forwarding rule
for incoming port 80 traffic.
3. The access point/router changes the destination IP address in the message to, for
example, 192.168.0.123 and sends the message to that computer.
4. Your web server at IP address 192.168.0.123 receives the request and sends a reply
message to your access point/router.
