Broadband connection

Urgently need help in the form of setup procedure for connecting Ubuntu to 1) Bigpond cable broadband & 2) Optus DSL broadband.

Hello.I use Optus DSL

Hello.I use Optus DSL broadband.I have an Ubuntu and WIndows XP Professional dualboot.I got Optus DSL broadband to work in Ubuntu by switching the Siemens Speedstream modem to NAPT mode in Windows.To do this,in Windows I entered the IP address of the modem (http://10.1.1.1/) in a web browser and in setup>mode I changed the mode to NAPT.This worked for me and now I am happily using the internet in Ubuntu.
