We don't use PPOE. Our network setup is DSL Modem -->ATM-->BLC (Occam)-->IP--->Router--->Transit provider. Basically we turn on the service and it's always running. We don't require any authentication or do any subscriber management on our users. I will start looking into the MTU issue though.

It sounds like that is a possibility. Are the DSL users being served by PPPoE? Setting the IP MTU on your PPPoE access template, depending on whose gear you're using to provide the servide provider end of your DSL services, to 1492 may help. jms
