I'm migrating from a PIX to a ASA and the PIX has the remote users PPTP to it. This is not pass though but the VPN type of the PIX. Does the ASA even support this? I have been trying to search around but all I have found is for allowing PPTP pass though.
PPTP is not a supported feature of ASA 5505 to my knowledge. As you mentioned, VPN pass through is available and instructions are widely available online.
