Problems with async PPP authentication on 2511

[DrGryphon]

Hi,

I have a cisco 2511RJ configured with a couple of modems. I have a local password database (with two simple entries) and a local IP address pool. When I dial up the modems handshake but ppp is not negotiated.

I have tried heaps of debug ppp commands but get no console output. This leads me to think I am missing something BIG but after looking through heaps of cisco sample configs I am left scratching my head.

I am lead to believe that I don't need to use AAA for local authentication.

Below is my config... I have tried about a thousand variations it seems Any help or ideas gratefully accepted.

in the Group-Async 1 interface, try disabling the TCP Header Compression, and specify only the authentication u support..

i'd start simple, with PAP, then move on.. otherwise, everything else looks alright..

good luck..
