Can a ASA5505 be used with PPOA DSL service? If so, how? The ASA5505 sits behind a PPOA DSL router/modem.
I would appreciate feedback.
If, Before 5505 if you put Router than YES otherwise NO.
Because if you are looking by question mark.. It is not supporting to ATM.
Put Router as a Perimeter and configure on it ATM by using guide below link.
