Hello Cyril,

see this example

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

Hello Cyril,

it is possible sorry for my misunderstanding

interface FastEthernet0/0

no ip address

speed auto


pppoe enable

pppoe-client dial-pool-number 1

this links to dialer interface

interface Dialer0

ip address negotiated

ip access-group 105 in

ip mtu 1454

ip nat outside

encapsulation ppp

ip tcp adjust-mss 1414

no ip mroute-cache

dialer pool 1

dialer idle-timeout 0

dialer-group 1

ppp authentication pap callin

ppp chap hostname johnroche

ppp chap password pppoeisgreat

ppp chap refuse


ip route Dialer0

on internal interface

int f0/1

ip address

ip nat inside

speed 100



ip nat inside source list 101 interface Dialer0 overload

access-list 101 permit ip any

Hope to help
