I have a Cisco 870 series router that I am using for internet access. I am having problems with PPPoE. I know that I have setup PPPoE correctly because I use the same settings on a 3COM router and it works fine. On the Cisco the CD and ppp indicators are lit. Some activity occurs from time to to time on the RXD and TXD lights. The ATM status is up yet I have no IP Address when I view the setup via SDM. Also NAT appears to be ok. I have attached file that details the present running-config. (please note that the ATM0.1 is down because phone cable is disconnected presently).Any suggestions would be welcome?
