How to get the IP address Of PPP adapter ????

NTDEV
1

Hi,

Could anyone tell me that in case of Dialup adapter on NT, after the PPP
negotiaition is done, how does the TCP/IP stack above get the IP address
which the PPP layer has dynamically got after the negotation???

I have implemented a TDI Filter driver in which i need to collect the IP
address assigned to the DialUp Adapter.How can a Filter driver come to
know that the adapter is on and is connected and has been assigned an IP
address??

Regards…

It is stored in NDIS_WAN_LINE_UP ProtocolBuffer. The format is undocumented
but rather easy to distinguish. You need NDIS IM driver to see this
notification (via ProtocolReceive).

See TdiRegisterAddressChangeHandler and TdiRegisterPnpHandlers.
