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

Are you receiving an IP address from your ISP?  Do a "show ip int brief" and see if dialer0 has an IP from your ISP.

Can you ping external websites from the router?

I would turn on the http servere and using the web interface and configuration wizard setup the whole thing. a few siimple click and you will be amazed at what happens.
you are missing quite a bit of the needed information from your posted config.
If this is your full config then do run the wizard from the web interface.
Type the IP in the web browser. It should be either 192.168.0.1 or 10.10.10.1
Good luck

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

If you have a pop blocker running it will stop the web interface from working correctlly.
