I am having difficult getting my DSL connection operational. I have a 2811 with a HWIC-1ADSL module with ios version 12.4. Below is a copy of part of my config.
Also the ATM is working but I not authenticating.
interface ATM0/3/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
pvc 0/32
encapsulation aal5mux ppp
Virtual-Template1
interface Virtual-Template1
ip address dhcp
ip mtu 1492
ppp authentication chap callout
ppp chap hostname XXXX
ppp chap password 0 XXXX
!
Any suggestions would be a great help.

Hi, most likely you need a pppoe configuration, not pppoa. Search "pppoe configuration example", there are many.

After looking around I changed it to this. But no change .
interface ATM0/3/0
description Qwest DSL circuit
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
pvc 0/32
encapsulation aal5mux ppp dialer
pppoe-client dial-pool-number 1
!
!
interface Vlan1
no ip address
!
interface Dialer1
ip address negotiated
encapsulation ppp
dialer pool 1
no cdp enable
ppp pap sent-username xxxx password 0 xxxx
!
I have included the results of the #show dsl interface atm 0/3/0 command as follows:
2811-gw#show dsl interface atm 0/3/0

I think my problem is authenitication. All the ISP is telling me we dont support that modem. and that it should be set to ppp chap.
thanks for the quick reply on the last posting.

s, as mentioned bdeof, you need to confirm with if it has to PPPoE, PPPoA, or both are supported. If it isn authentication problem, this show with "debug ppp auth" and "term mon".
