I agree - there's no need to worry about port compatibility, so long as you've got yourself an Ethernet port. I have Verizon PPPoE DSL, and I use a MacSense XSense MIH-120 (I'm relatively sure that's the model number) four-port router. It's a wonderful little device, and what's best is that you can go into a web browser window and configure the router to handle the PPPoE handshaking so you don't ever need to use the MacPoET or other PPPoE connecting application.
