Hello Cyril,

see this example

https://www.cisco.com/en/US/products/hw/routers/ps380/products_configuration_example09186a0080094475.shtml

you don't need the vpdn part if your IOS is recent.

username and password has to be added to dialer interface configuration with commands like

int dialer 1

ppp authentication chap pap

you can configure username and password using

username xxx password yyy

in global config mode

Hope to help

Giuseppe

dialer-group 1

ppp authentication pap callin

ppp chap hostname johnroche

ppp chap password pppoeisgreat

ppp chap refuse

!

ip route 0.0.0.0 0.0.0.0 Dialer0

on internal interface

int f0/1

ip address 192.168.11.250 255.255.255.0

ip nat inside

!

ip nat inside source list 101 interface Dialer0 overload
