Manage Port Forwarding to a Local Server for Services and
Applications
If a server is part of your network, 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 default DMZ server to which the
modem router
forwards all other incoming protocols (see
Set Up a Default DMZ Server
on page 217).
Forward Incoming Traffic for a Default Service or Application
You can forward traffic for a default service or application to a computer on your network.
To forward incoming traffic for a default service or application:
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 provide the service.
The server computer must always receive the same IP address. To specify this setting, use the
reserved IP address feature. See
Manage Reserved LAN IP Addresses
on page 222.
3.
Launch an Internet browser from a computer or WiFi device that is connected to the network.

Add a Port Forwarding Rule with a Custom Service or
Application

modem router
lists default services and applications that you can use in port forwarding rules. If the
service or application is not predefined, you can add a port forwarding rule with a custom service or
application.
To add a port forwarding rule with a custom service or application:
1.
Find out which port number or range of numbers the service or application uses.
You can usually find this information by contacting the publisher of the service or application or through
user groups or news groups.
