AirPort 1.3 has a PPPoE feature, so there is no need for a separate PPPoE application in order to connect to the Internet. With AirPort 1.3, you cannot enter a private network address (in the range 192.x.x.x) into an AirPort Base Station. This article tells how to set up an AirPort Base Station with AirPort 1.3 software and PPPoE to connect to the Internet.

Some Internet Service Providers (ISP) who require PPPoE for their DSL service may require that a private 192.x.x.x IP address be assigned to the AirPort Base Station. These ISPs use a PPPoE application (for example, MacPoET) for authentication purposes. In the past, to use the PPPoE application, the client had to be set up with a private static IP address of 192.x.x.x. However, AirPort 1.3 software includes a PPPoE feature and no longer requires a separate PPPoE application.

An ISP might not know that you are using an AirPort Base Station with AirPort 1.3. Because of this, they may try to have you enter a private IP 192.x.x.x address into the AirPort Admin Utility. However, AirPort 1.3 does not allow you to manually assign an IP address.

Follow these steps to set up an AirPort Base Station with AirPort 1.3 software and PPPoE for a connection to the Internet:

1. Open the AirPort Admin Utility and select your Base Station.

2. Click Configure and enter your password.

3. Click the Internet tab.

4. Choose PPP over Ethernet (PPPoE) from the Connect using pop-up menu.

5. If required by your ISP, enter your user name, password and service name in the appropriate fields.

6. Click Update.

7. After the base station restarts itself, quit the AirPort Admin Utility.

Note that you can also configure the AirPort Base Station to connect automatically. In that case, simply open your Web browser (or other Internet-based application) to connect to your ISP.
