AC1750 Smart WiFi Router Model R6350 Application Example: Make a Local Web Server Public 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 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: 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 192.168.1.123 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 router. Manage Port Forwarding and 182 Port Triggering User Manual

Application Example: Make a Local Web Server Public
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
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:
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 192.168.1.123 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 router.
