ASA 5505 PPPoE via DSL

Unanswered Question
Feb 10th, 2009

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.


I have this problem too.

The "known good" credentials, weren't.

Testing the new config....

It works, using PAP authentication.

It was a bad PPPoE username.
