Hi there,
The goal is to configure (from scratch)  and connect a modem/router ADSL Cisco 837 to the Belgian ISP Skynet/Belgacom
The subscription is a standard "Belgacom Favorite package" (Dynamic IP, PPPoE,  PVC 8/35, etc ...)

=> http://www.belgacom.be/private/en/jsp/dynamic/productCategory.jsp?dcrName=internet_access_withvoice&mc_id=adw_cbu_B_B1_1

Since I am not used with the Cisco ISO CLI, could somebody give my some help to write a basic config (PPPoE Internet connection + NAT) to connect this 837 Cisco router ?
Many thanks
