Hi David

I spent last weekend working on configurng both a Cisco 837 and 877 ADSL rotuer to access my ISP. This was the first time I have ever tried this and I also posted on the forum looking for help.

I received some extremely helpful replies from a forum member "Edison Ortiz" with links to documents which help with this configuration and with troubleshooting problems.

The post appears to have vanished (at least I can't find it. However here are the links provided by Edison

For configuration: http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a729.shtml

For Troubleshooting: http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a7c2.shtml

Now I am no expert at this as I said above but looking at your configuration, something that I did notice was that there are no global Point to Point over ethernet (pppoe) parameters configured (see section 4 on the configuration link).

In the configs that worked fro me over the weekend, I had the following lines of configuration.

On the 837 which received an IP address from the ISP dynamically:

vpdn enable

!

vpdn-group 1

!

request-dialin

protocol pppoe

!

On the 877 which has a static IP address assigned by ISP:

vpdn enable

!

vpdn-group 1

Your configuration looks pretty complex (to me anyway) and there are parts of this I don't quite understand. However if it was at all possible, it maybe worth while (if the addition of the pppoe parameters don't work) to start with a simpler configuration and then when you have all the basics working, adding the rest of the configuration back in.

Maybe this will help a little.

Michael.
