I'm switching away from xnet and going through a wireless setup through my workplace (antenna on the roof).  So the ADSL disappears completely.  I still need the WAG54GP2 router to act as a local wireless network.

I notice in the WAG54GP2 there is a setting "Router Mode", is this what I want?
How do I make all data received from the wiress network forward onto a new gateway (not PVC1).
