Hi all,
i've a strange problem with a Cisco 827.
It is configured on a Adsl connection with 8 static ip addresses, auth is PPPoA and encapsulation mux.
The router correctly connects to Internet and everything seems to go fine.
after a while (1 minute or 1 hour or more) Atm goes down so the Dialer Interface tries to connect again.
After some disconnections and reconnections, the Virtual-access1 interface remains down and there is no way other than reload to pull it up again. I tried to shut/no shut the Atm interface but only a reload can solve.
What is that "Vi1 PPP: Authorization NOT required" that can be read below in console log ? It could be the real problem, but i'm not sure.
Can somebody help me to solve this behaviour ?
Thanks for any answer.
