ndiswan pptp interface for WAN miniport driver

Hi,

Can anyone give me some directions on the ndiswan pptp
interface for developing VPN WAN miniport? I looked
through the whole MSDN library about pptp or vpn but
haven't seen much about how to develop such a miniport
driver to work with ndiswan pptp. Specifically as a WAN
miniport driver, how to send received WAN packets to the
TCP/IP layer, and from where to receive their reply
packets?

Thanks,
NG

The above section in the DDK has the details on implementing a WAN miniport
driver.

Also, you can look into the TDI drivers on how to interact with the
transport from a miniport.

L2TP in w2k is NDISCoWAN miniport, with TAPI support (make call/handle
incoming call) implemented in CoNDIS call manager callbacks (as
usually, well-documented in MSDN).

This is the upper edge. The lower edge is a TDI client, which talks to
raw socket interface in IP.

PPTP uses obsolete NDISTAPI support on the upper edge and IIRC not a
CoWAN miniport.

Product link to WAN Tunneling Framework. The sample
implementation is an L2TP WAN miniport that runs on
9x/NT/2000/XP.
