cisco 837 configuration
Hi I have a cisco 837 adsl router. My internet connection is with Pipex and I have a dynamic IP. I have configured it in as far as all my hosts can comunicate with each other and the router through ping tests on my LAN. But I cannot connect to the internet! Please help! Ping tests to external IP addresses and external hostnames fail!!!
My configuration is below. My ISP uses PPPOA. Please tell me what I am doing wrong!!
Thanks
Barry

Hi Guys,
Thanks for your helpful comments. I tried using the web browser interface but I just keep on getting the message contacting router. And it doesn't progress any further. My entire config has been posted! If I am missing some commands could you possibly tell me what they are so I can configure it from the command line???
I will try the show ip int brief command. But anyone if anyone has a working example, I would appreciate it if they could post it up. Or any other useful comments would be appreciated
Cheers
Barry

Sorry, bit of a mistake! The accepted answer was the one by from MarkDozier Date: 10/17/2004 12:42AM PDT and the assisted was from MarkDozier Date: 10/17/2004 11:27PM PDT. Either way both answers resolved my problem!! Thankyou so much!! And thanks for KFrederick for his helpful comments!! You guys certainly know your stuff! Now I can concentrate on trying to become a CCNA :)
Can you ping external websites from the router?
