Wondering if someone can see if I have made a simple mistake with my config. It has authenticated ok and been assinged an Internet IP address from the ISP but the clients can not connect ping any internet address nor can the router.
Any help welcome , thanks

Leo,
Hmmm, I do not believe that the command you suggested is necessary.
What I see here is a grave error in the configuration: you have your CEF and IP routing deactivated. No surprise, then, that your router is not routing your packets. Please enter the following commands to the global configuration:
ip routing
ip cef
Please verify your connectivity after entering these two commands, and also please post your configuration anew (I am concerned about the no ip route-cache commands on your interfaces but I silently expect that these commands will automatically be removed after reactivating the routing).
Also, I suspect that the deactivation of IP routing is caused by a misleading document on Cisco website - this is perhaps the third time a person here on CSC is seeking support for ATM/ADSL connectivity, and the problem has the same traits. Did you follow a specific Cisco document when configuring your router?
Best regards,
Peter

Under your ATM sub-interface, where's "protocol ppp dialer"?

I got the ATM part and dialer part of the ISP so thought it would be ok like that. It connects and get assinged IP from ISP but i thought maybe route or ACL or nat part was not correct. Will give it a try ..

Hi,
enter this command: ip routing
Regards.

Thanks Peter, this has sorted the issue. You are right I followed a document on the cisco website for this but failed to pickup on the no ip route in the config.
