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 gateway always gives your web server an IP address of
192.168.0.33.
2.
In the Port Forwarding/Port Triggering screen, configure the gateway 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 in the
Dynamic DNS screen of the gateway.

For more information, see
Dynamic DNS
on page
85.
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 Internet service provider assigned, which typically changes.
How the Gateway 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 gateway.
Destination port number
. 80, which is the standard port number for a web server
process.
2.
Your gateway receives the message and finds your port forwarding rule for incoming port 80
traffic.
3.
The gateway changes the destination in the message to IP address 192.168.0.223 and
sends the message to that computer.
4.
Your web server at IP address 192.168.0.223 receives the request and sends a reply
message to your gateway.
5.
Your gateway performs Network Address Translation (NAT) on the source IP address and
sends the reply through the Internet to the computer or wireless device that sent the web
page request.
Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
An application uses port forwarding to more than one local computer (but not
simultaneously).
An application opens incoming ports that are different from the outgoing port.
With port triggering, the gateway monitors traffic to the Internet from an outbound “trigger”
port that you specify. For outbound traffic from that port, the gateway saves the IP address of
the computer that sent the traffic. The gateway temporarily opens the incoming port or ports
that you specify in your rule, and forwards that incoming traffic to that destination.
Port forwarding creates a static mapping of a port number or range of ports to a single local
computer. Port triggering can dynamically open ports to any computer when needed and
close the ports when they are no longer needed.

Note:
If you enabled port triggering because you use applications such as
multiplayer gaming, peer-to-peer connections, real-time
communications such as instant messaging, or remote assistance (a
feature in Windows XP), enable Universal Plug and Play (UPnP). See
Improve Network Connections with Universal Plug and Play

Add a Port Triggering Service
To add a port triggering service:
1.
Launch a web browser from a computer or wireless device that is connected to the
network.
2.
Type
http://routerlogin.net
or
www.routerlogin.com
.
A login screen displays.
3.
Enter the gateway user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
The BASIC Home screen displays.

Single address
restricts the service to a particular computer. You must enter the IP
address of the computer to which you want to grant access.
9.
From the
Service Type
list, select a service.
If you are not sure, select
TCP/UDP
.
10.
In the
Triggering Port
field, enter the number of the outbound traffic port that will open the
inbound ports.

In the
Connection Type
,
Starting Port
, and
Ending Port
fields, enter the inbound
connection port information.
12.
Click the
Apply
button.
The service is added. You must enable port triggering before the gateway uses port
triggering. For information about port triggering, see
Set the Port Triggering Timeout
on
page
