is that correct ?.
Sounds about right.

No. Doesn't sound right. The PPPoE connection will presumably signal Smoothwall when the connection is lost. DSLAMs aren't IP devices, they aren't ICMP-PINGable.

A complete description of how PPPoE works is here
https://tools.ietf.org/html/rfc2516No, it is not IP-based, PPPoE works with Ethernet frames and MAC addresses.

You can.
