Having trouble offloading packets to the ATM interface I think, I have had confirmation that the PPP connection has successfully authenticated with the ISP (Easynet uk) however I still can not ping IP addresses or Host names on the internet in fact I can not ping the name servers themselves!

I have been looking at this for a while now and would appreciate it if one of you guys could give me a few ideas.

Thanks in advance.

Please post a "sh int"...this will perhaps give us a clue (for example, things to look for are the virtual-access bound to a dialer 0 interface)...maybe access-list 103 permit ip any any?
