8-10 Using the Manager Interface to Configure the Router for Internet Access

Configuration for Local Servers

Although NAT 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. 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 bottom of Menu 15, although you are not limited to these choices. See IETF

RFC1700, “Assigned Numbers,” for port numbers for common protocols..

Use Menu 15, SUA Server Setup, to configure the router to forward incoming protocols to IP

addresses on your local network based on the port number. In addition to servers for specific

protocols, you can also specify a default (DMZ) server to which all other incoming protocols are

forwarded. To configure port forwarding to a local server:

Enter a port number in an unused Start Port row.

To forward only one port, enter it again in the End Port row. To specify a range of ports, enter

the last port to be forwarded in the End Port row.

Enter the IP address of the local server in the corresponding IP Address row.

Press [Enter] at the Press ENTER to Confirm... prompt to confirm your selections, and return

to the previous menu.

Press [Esc] at any time to cancel your selections.

Menu 15 - SUA Server Setup is shown in Figure 8-6.

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.
