Application Example: Make a Local Web Server Public

Page 238 highlights

Nighthawk DST AC1900 DST Router and DST Adpater Model R7300DST The rule is removed from the table. 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 DST router always gives your web server an IP address of 192.168.1.33. 2. On the Port Forwarding / Port Triggering page, configure the DST 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 in the Dynamic DNS page of the DST router. Dynamic DNS makes it much easier to access a server from the Internet because you can type the name in the Internet browser. Otherwise, you must know the IP address that the ISP assigned, which typically changes. How the DST Router Implements the Port Forwarding Rule The following sequence shows the effects of a port forwarding rule: 1. When you type 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 DST router. • Destination port number. 80, which is the standard port number for a web server process. 2. Your DST router receives the message and finds your port forwarding rule for incoming port 80 traffic. 3. The DST router changes the destination in the message to IP address 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 DST router. 5. Your DST router performs Network Address Translation (NAT) on the source IP address, and sends the reply through the Internet to the computer or WiFi device that sent the web page request.

The rule is removed from the table.
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 DST router always gives your web server an IP address of
192.168.1.33.
2.
On the Port Forwarding / Port Triggering page, configure the DST 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 in the
Dynamic DNS page of the DST router.
Dynamic DNS makes it much easier to access a server from the Internet because you
can type the name in the Internet browser. Otherwise, you must know the IP address that
the ISP assigned, which typically changes.
How the DST Router Implements the Port Forwarding Rule
The following sequence shows the effects of a port forwarding rule:
1.
When you type 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 DST router.
Destination port number
. 80, which is the standard port number for a web server
process.
2.
Your DST router receives the message and finds your port forwarding rule for incoming port
80 traffic.
3.
The DST router changes the destination in the message to IP address 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 DST router.
5.
Your DST router performs Network Address Translation (NAT) on the source IP address,
and sends the reply through the Internet to the computer or WiFi device that sent the web
page request.
