Hi gurus! I need help! I just bought a Cisco 857 router. It's running IOS 12.3. I ran through the SDM intitial configuration and entered all the info it requires from my ISP. This is PPPoA ADSL and the ISP is supposed to pass out a public IP to my router after I athenticate to their network. I am told by the ISP that authenication occurs properly, and that they are indeed assigning an IP address, but I can't see that the router is actually getting and assigning the IP to an interface (I think it should be listed on Dialer0 which is somehow associated to sub int ATM0.1). I hope I've listed enough detail! My config file follows. Thanks in advance for your help!

Nevermind...I should be using PPP/PPCP instead of DHCP on the Dialer0 interface.
 
Correct---"ip add negotiated" I believe is the correct command. Hope this helps. Looks like you have it figured out.
