I've been playing around my wla-g54 (just a bridge) and I cannot get the pppoe working using just the normal ethernet ports there.

Is it even possible to have it working (ip-wise I don't see any obstacles) since this box doesn't have 'wan' interface?

Anyways, I'm getting pppoe timeout messages. PPPoE from my xp machine works nicely, goes thru the same box.
