Hello all

I've been battling this issue for two days now and now I'm compelled to ask for help. I'm a t-online subscriber in Germany and I've tried almost every config I could, but the ADSL just doesn't want to connect. Here is the config. I appreciate any helpful insight.

Thanks for your time.

P.S the shown config I made with CRWS, because I gave up manually trying.

Hello,

1. Do not use CRWS

2. For germany t-dsl connectivity you have to use different settings on your ATO0 Int:

!

interface ATM0

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

ip route-cache flow

no atm ilmi-keepalive

dsl operating-mode auto

!

interface ATM0.1 point-to-point

pvc 1/32

pppoe-client dial-pool-number 1

!

!

3. We need additional information if it sill doesn't work, ie cabeling, output from "sh run", interface status, output on console, output from "debug ppp authen" ...

regards

Matthias

Bingo, right on!, thanks a lot for the help I was battling this problem for the past 8 months (insgesamt). I actually gave up on a 827 configration because of the same problem.

Thanks again

hello again

Can you please explain to me why the deutsche Telecom needs a ATM0 sub interface to function instead of just a regular config, such as the one I had.

Thanks
