Step−by−Step Configuration of PPPoE with a Static IP

Address

Your Internet Service Provider (ISP) has assigned a static public IP address to your Cisco Digital Subscriber

Line (DSL) Router.

Note: A color code is used to relate tasks in this section with examples of configurations in the Configuration

section. Configurations are color−coded as follows: Dynamic Host Configuration Protocol (DHCP) Server,

Network Address Translation (NAT).

Step−by−Step Configuration

Important: Before you begin, close all programs on the PC that might be monitoring your COM port.

Devices such as PDAs and digital cameras often place programs in the system tray that will render your COM

port unusable for configuring your Cisco DSL Router.

Connect the Cisco DSL Router and Your PC

A console connection is made with a rolled cable and connects the console port of the Cisco DSL Router to a

COM port on a PC. The console cable that is included with the Cisco DSL Router is a flat light blue cable.

For more information on the pinouts of a rolled cable, or the pinouts of an RJ−45 to DB9 converter, see the

Cabling Guide for Console and AUX Ports.

Connect the RJ−45 connector on one end of a Cisco console cable to the console port of the Cisco

DSL Router.

Connect the RJ−45 connector at the other end of the console cable to an RJ−45 to DB9 converter.2.
