PPP authentication during callback

Unanswered Question
Apr 16th, 2007


on Cisco 1841 I have the following configuration:

interface Dialer1

dialer string 7020191191

dialer caller 0257517627 callback

ppp authentication chap callin


When I generate traffic from local LAN to an external IP address in order to trigger ISDN call, PPP authentication is working well.

In a callback scenario (ISDN call received by 0257517627) the router tries to perform remote authentication even if the callback to 7020191191 is considered as call-out and PPP authentication doesn't work.

How can I fix this problem?

Best regards
