How the AP implements a port forwarding rule [router
mode]
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 AP.
•
Destination port number. 80, which is the standard port number for a web server
process.
2. The AP receives the message and finds your port forwarding rule for incoming port
80 traffic.
3. The AP changes the destination IP address in the message to, for example,
192.168.1.123 and sends the message to that computer.
4. Your web server at IP address 192.168.1.123 receives the request and sends a reply
message to your AP.
5. Your AP 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.
Application example: Make a local web server public [router
mode]
If the AP is in router mode and 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
address reservation.
In this example, your AP always assigns your web server an IP address of 192.168.1.33.
2. On the Port Forwarding / Port Triggering page, configure the AP 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 AP.
