Here's something which is probably quite obvious to the experts but kept me firewalled from the network for a frustrating period.

My Speedstream 4200 hung up after a power spike and would not connect at all so I had to factory reset it and configure from a previously printed copy of 'how to manually configure' from the Optus site.

After re-configuration I had a functional browser but firewalled Limewire (Frostwire).

If you are trying to find the manual process on the Optus website and you end up at this link..

Optus myZOO DSL Help - Siemens SpeedStream 4200 Ethernet: Windows XP

It misses out one piece of critical information which is at this link ..

Being that you have to configure the modem for Optus Bridge under the Setup -> Mode menu item.
