I have at Cisco 2620 running 12.1 with a 4 port IMA card. I have an ATM link to my DSLAM and am trying to get PPPOE workng but am having no luck. Any help would be appreciated. I would consider paying a consultant.
Thanks

here are two sample configs, one with atm interface and ppoe, and one with an ethernet interface and ppoe. search the cisco site for 800 series router configs for atm and ppoe information.
