Set Up Port Forwarding to a Local Server
If your home network includes a server, you can allow certain types of incoming traffic to 
reach the server. For example, you might want to make a local web server, FTP server, or 
game server visible and available to the Internet.
The modem router can forward incoming traffic with specific protocols to computers on your  local network. 
 You can specify the servers for applications and you can also specify a d\
efault 
DMZ server to which the modem router forwards all other incoming protoco\
ls.
To forward specific incoming protocols:
1.  Decide which type of service, application, or game you want to provide.
2.  Find the local IP address of the computer on your network that will prov\
ide the service.
The server computer must always use the same IP address. To specify this setting, use  the reserved IP address feature. See Reserve LAN IP Addresses  on page
  55.
3.  Launch a web browser from a computer or wireless device that is connecte\
d to the network.
4.  T
ype  http://routerlogin.net.
A login window opens.
5.  Enter the modem router  user name and password.

 Address field, enter the IP address of the computer that will provide the 
service. 
10.  Click the  Add button.
The service displays in the list.
Add a Custom Port Forwarding Service
To add a custom service:

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 modem router always gives your web server an IP address of 
192.168.0.33. 
2. In the Port Forwarding/Port Triggering page, configure the modem 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 in the 
Dynamic DNS page of the modem router. 
For more information, see Dynamic DNS on page 64.
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 provider assigned, which typically changes.
How the Modem 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 modem router.
