cisco 803 auth-problem using chap for dsl

Hello.

First I would like to apologize for my bad English. And for this extensive posting ;-)

And now to the problem: I am trying do establish a DSL-connection using the cisco router 803. Provider: arcor (Germany/Berlin)

Sync etc. is ok. Only there seems to be a problem with the authentication. The provider only supports chap (took me a time to find that out ;-))

The first try to establish a connection is refused: "Authentication failure" The next one (a few seconds later) is apparently OK, but the line is restricted (because of the previous auth-failure):

- not even the gateway can be pinged

- sending a http get request to a arbitrary IP gets only a redirect to

formatting link
seems to be a "feature" of the provider ;-) Anyway this shows that all technical stuff seem to be OK - only a auth-problem

If anyone is having some suggestions, please post them - I tried a lot, but had no success.

The username/password are really OK ;-) I tried them using a quick setup on a Linux-box (the debug-output of that connection at the end of the posting)

Gratefully for each assistance Klaus

And here some informations and debug output:
