!--- To change from PPP CHAP to PPP PAP,

!--- ppp chap password 
!--- with the following two lines:
!--- ppp authentication pap callin
!--- ppp pap sent-username password 
!--- For NAT we are going to overload on the Dialer1 
!--- interface and add a default route out 
!--- since dialer ip address can change.
