Wag54g Bridged mode

Sorry if this has been asked before I search over the forums over the last 6 month and found nothing. I was wondering on were to find information on how to setup the Wag54g in bridged mode to work on the BT network (using PPPOA). I am trying to get PFsense to connect, but I have tryed setting up a PPOE connection on my laptop to connect. The laptop was using wireless. I only have 1 dynamic ip address so I don't know if this will render this idear not possible.

Thanks for the help in advanced
