It probably is setting up pppoe, but the addresses are put into the config part of the Mac program. I need to know where to put them in the pppoe program under linux.

Well actually, I did get it to work without using pppoe, simply by setting the IP address of the NIC to the static IP address and the correct gateway route, so I suspect that it must be the old (3) style (either that or I am even more confused !). In any event, we're upgrading the speed of the line in the next week or so and will probably be in Layer2 mode then, and will need pppoe for sure then.

I understand this a bit better now. One additional question, if I want to use the same network card for both the internal LAN and the adsl, then I set up eth0 to have no IP address and an "alias" ie eth0:0 for the LAN. Is this correct or should they be eth0:0 and eth0:1?
