Mac OS X 10.4: How to use a PPPoE connection while maintaining Bonjour for local network devices

If you use a PPPoE connection to your Internet service provider in Mac OS X 10.4, follow these steps if you wish to maintain Bonjour connections to your other local network devices while connected to your ISP, such as a network-based printer or another local Mac sharing music through iTunes.

1. From the Apple menu, choose System Preferences.
2. From the View menu, choose Network.
3. From the "Show:" pop-up menu, choose "Network Port Configurations".
4. Click "New...".
5. From the "Port:" pop-up menu, choose the same network port you are using for your PPPoE connection.
6. Name the new port the name in the "Port:" pop up menu and append DHCP at the end, for example "Built-in Ethernet DHCP".
7. From the "Show:" pop-up menu, choose the new port you have just created.
8. Click the TCP/IP tab.
9. Make sure that the value for the "Configure IPv4" pop-up menu is "Using DHCP".

This will allow your Mac to establish your PPPoE client connection to your ISP and continue to have local DHCP addressing to communicate to your local network devices.
