CHAP authentication failure:

[shechter]

Hello all,

I try to configure DDR.

When using ppp chap hostname + password on the BRI interface, all is working just fine.

When using the same configuration with dialer the remore router recieves Authentication failure.

Is there any diff between BRI and dialer ppp chap authentication?

Using BRI only work perfect!

But using dialer with same configuration does not work. It fales on chap authentication.
