Thanks GG for the link to the Thompson manual. It goes a little further in some areas than the one hidden on the installation CD with the Telstra Australia badged version which appears to be a special edited edition (if not a complete re-write) to suit the Telstra regime.
I did note that the Thomson version uses the more usual address of
http://192.168.1.254 to get into the configuration page for the device. The 'Telstra' version uses
http://10.0.0.138. Exactly why is not apparent, but most Australians will understand that it's not altogether uncommon to use "why" and "Telstra" in the same sentence
.
