Re: Routing problem...
Not all DSL connections require PPPoE.
With my provider, both at work, and at a user's home we have SDSL connections. The router we were provided works as if it were a real ethernet router. I just plug in a cable, configure my ip addresses and go. With this service I have not needed to use pppoe, nor mess with MTUs.
Fyi,
