I would recommend switching to Mandrake 9.1. It sets up PPPoE for you during install
True but you'll learn nothing at all.
Merlin371: if you want to share you connection to other computer, you'll need to set up a NAT with Iptables. It seems harder as it is in reality. Search on forum or google and you should find a lot of docu 'bout it. A computer acting as a NAT can be setted as the default gateway to computer around him.
Mine is working damn great :P
