5-6 Advanced Configuration of the Router

Configuring for Port Forwarding to Local Servers

Although the router causes your entire local network to appear as a single machine to the Internet,

you can make local servers for different services (for example, FTP or HTTP) visible and available

to the Internet. This is done using the PORTS menu. From the Main Menu of the browser

interface, under Advanced, click on PORTS to view the port forwarding screen, shown in

Figure 5-2

Figure 5-2. Port Forwarding Menu

Requested services are identified by port numbers in an incoming IP packet. For example, a packet

that is sent to the external IP address of your router and destined for port number 80 is an HTTP

(Web server) request, and port 21 is an FTP request. Examples of port numbers are shown at the

top of the PORTS menu, although you are not limited to these choices. See IETF RFC1700,

“Assigned Numbers,” for port numbers for common protocols..

Note:

Many residential broadband ISP accounts do not allow you to run any server

processes (such as a Web or FTP server) from your location. Your ISP may periodically

check for servers and may suspend your account if it discovers any active services at

your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
