Set Up Port Forwarding to a Local Server

If you have a server in your home 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.



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 provide the service.

The server computer must always have the same IP address. To specify this setting, use

the reserved IP address feature. See

Reserve LAN IP Addresses
