If I understand your problem, you cannot connect to the Internet by using a shared DSL connection That uses PPP over Ethernet (PPPoP)?
When connecting to the Internet through a shared DSL network connection, and the DSL connection uses PPPoE, you may not be able to connect to the Internet. This occurs if the PPPoE connection is configured for DSL instead of for a local area network (LAN).
To corrrect behavior, configure the PPPoE connection for use on a LAN:
On the computer that hasthe DSL connection, click Start, | Settings | Control Panel.
Double-click Network and Dial-up Connections.
Three local-area connections are listed: one for the LAN, one for the DSL network interface card (NIC), and one for the PPPoE connection.Right-click the PPPoE connection, click Properties, and then click the Sharing tab.
Click Enable Internet Connection Sharing for this connection, click For Local Network, and then click Local Area Connection.
Click OK.
Right-click the LAN connection, click Properties, click Internet Protocol, and then click Properties.
Verify the IP address is 192.168.0.1, and then click Cancel. Verify that the computer can gain access to the Internet.Restart the client computers, and verify that they also can gain access to the Internet. Hope this provides the answer.
