Hi,

I am setting up a Cisco 857 for adsl that does not require authentication according to the ISP. I have got a connection on the ATM0 interface but am not getting a PPP connection?! I have not configured any type of authentication on the dialer interface.

When i run 'debug ppp authentication' I receive

vi2 ppp Authorization required
vi2 ppp no remote authentication for call-outs

Can anyone help?

Many Thanks

Step 1. a) Connect to your router using Telnet, SSH or via console.

b) Enter the global configuration mode using the command:

Router(config)#enable
Step 2. Enable the router's HTTP/HTTPS server, using the following IOS commands.

If http/hhtps is enabled and configured to use non standard port numbers, you can skip this step and simply use the port number configured already.

Router(config)# ip http server
Router(config)# ip http secure-server
Router(config)# ip http authentication local
Note: HTTPS is enabled only for crypto enabled IOS images.

Step 3. Create a user with privilege level 15.

Router(config)# username <username> privilege 15 password 0 <password>
Note: Replace <username> and <password> with the username and password that you want to configure.

Step 4. Configure SSH and Telnet for local login and privilege level 15:

Router(config)# line vty 0 4
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# exit
Step 5. (Optional) Enable local logging to support the log monitoring function:

Router(config)# logging buffered 51200 warning
I hope this helps..Booda2us

Sorry I dont understand, this looks like how to gain access to the routers web interface. The problem that I am having is that the router will not connect to the internet. I have been told by my isp that it does not require any authentication (chap or pap). When i run the debugging i get the above errors

Can you post running configuration from the router?

Also, provide the information you received fromt he ISP, VPI/VC, IP Address etc.

Hi,

Sorry for the late reply. This problem has been sorted, it was due to the lack of information supplied by the ISP.

Thanks

No, it was due to the connection not using ppp. It's configured directly on the atm interface with a private hidden ip address directly to the isp (its own form of authentication)
