I have purchased a Cisco 1941 with an Ehwic adsl2 card that I am trying to set up to work with my ISP. Unfortunately my ISP does not deal with commercial gear with DSL normally so we are having issues. Now it's time to ask the pros as I am just learning about this technology. Attached is my script if anyone can help or tell me why I can sync to the DSLAM but not get to the internet.

 

Thanks,

Can the router itself ping the internet at all or is it internal clients that can't access the internet, I don't see any NAT in the Config either unless I'm missing something. Not sure you'd need a default gateway as you have setup gateway of last resort.

 

No experience with ATM however, hopefully below link will help you a bit.

Thank you for the response. I'm not sure why the script did not copy and paste properly but below you will see the one that is currently in the router. Also it will not ping the internet from inside the router. I have tested it both thru the CLI console connection and with a laptop connected directly to the G0/0 port. Along with this I have a 3750G with wireless controller that will be part of my network. Another thing that I am not sure about is all of the scripts I see on forums about this have a dialer and also do not have the E0/0/0 ports shown. This E0/0/0 is a virtual port I believe that creates when the ATM is in use. However when you do a "ip int brief" it is almost never "UP" or the protocol is almost never "UP" either.

 

Thanks,
