a. Select Standard.
If your Service Type is RoadRunner and your RoadRunner region requires the login program:
a. Select the RoadRunner login program used in your region.
b. Enter the login name and password provided by RoadRunner.
c. If RoadRunner provided an authentication server address, enter it as Login Server
IP address. Otherwise, leave this field as 0.0.0.0.
5. Use the space bar to toggle the IP Address Assignment field to Static or Dynamic.
If your service provider has assigned you an IP address to be manually configured in your PC,
select Static. In this case, enter your assigned IP address, subnet mask, and gateway address
(the address of the ISP’s router). If you do not know the gateway address, leave this field as
0.0.0.0.
6. Use the space bar to toggle the Single User Account field to Yes.
7. Press [Enter] at the Press ENTER to Confirm... prompt to confirm your selections.
You can press [Esc] at any time to cancel your selections. When you save this menu, the router
automatically creates a default static route to the ISP.
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..
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.
