Cisco ASA 5505 PPPoE via DSL

Having trouble getting a public IP on the outside interface.

ASA 5505 running 8.0(2)
Westell E90610030-06 DSL box running current firmware.
Service provider is AT&T (Bellsouth)

DSL modem is in bridge mode.
Outside interface of 5505 is set to PPPoE with known good credentials.
I've tried CHAP and PAP authentication.

Last attempt, using MAC cloning, showed a PPPoE address of in the client monitor in ASDM. Authentication is still set to CHAP.

I've read that AT&T does a 2-hour IP lease, so my next step is to shut down the DSL router for 2 hours and try again.

I believe PPPoE debug is still broken in this ASA version, unfortunately.

It works, using PAP authentication.

It was a bad PPPoE username.
