By default, the modem blocks inbound traffic from the Internet to your computers except
for replies to your outbound traffic. To allow remote computers on the Internet to access
a computer on your local network, you might need to create exceptions to this rule.
Port forwarding is an advanced feature that affects the behavior of the firewall in the
modem. By enabling port forwarding, you can make local computers or servers available
to the Internet for different services. Port forwarding is designed for FTP servers, HTTP
web servers, and other server-based applications and services. After you set up port
forwarding, requests from the Internet are forwarded to the specified server.
Before you start, determine which type of service or application you want to provide
and the local IP address of the computer that must provide the service.
The following sections provide information about managing port forwarding for incoming
traffic:

Enable Port Forwarding and Add a Service or Application
Before you add a service or application, first determine which port number and protocol
the service or application uses. You can usually find this information by contacting the
publisher of the service or application or searching the Internet.
WARNING:
Enabling port forwarding creates a security risk. If you do not need port
forwarding, keep it disabled, which is the default setting.
To enable port forwarding and add a service or application for port forwarding:
1. Launch a web browser from a device that is connected to the modem.
The device can be a computer that is directly connected to the modem or a client
from a router that is connected to the modem.
2. In the address field of your browser, enter http://192.168.5.1.
The limited Dashboard page displays.
3. If you did not select the Remember me check box when you logged in previously,
enter the modem password in the Sign In field.
See the modem label for the default password.
4. Click the Sign In button.
The full Dashboard page displays.
5. Select Settings > Advanced > Port Forwarding.
