Hi All,
Is it possible to have a NDIS IM between NDISWAN and WAN miniport?
Basically I’am looking at having a layer which modifies the PPP data
before actually sending it to WAN miniport. Is there any other
approach to achieve this functionality?
Any URLs/Links for resources/information related to this will be
helpful.
Thanks,
Rajiv.
If you question is
‘…if one can have an IM driver that will allow it to
function with NDISWAN adapters over TCP/IP…’
then the answer is yes.
If you are using the newest IMSAMP sources it should work.
Just make sure that your that the phone book entry
you are using to dial has “IP header compression”
disabled.
With Win2K onwards you will have to change your NDISWAN miniport
to a CoNDISWAN miniport.
Hope this helps.
Hi,
Thanks for the reply.
Can you please clarify:
WAN Card (h/w)
Any limitations on NDIS & OS Versions? I read in some website (I
think
in Microsoft site) that IM does not bind to NDISWAN in 9x & NT.
Are you aware of any such limitations.
A more general question, Is it possible to have a IM bound to only
one of the Miniport (when multiple miniports are present)? If so,
any links/inputs on this would be great.
Thanks,
Rajiv.

Hi
The article at Microsoft is correct, those O/S do not support NDISWAN
bindings. We gave up writing drivers for those O/S’s. However at
www.pcausa.com, they have a generic hooking driver that was more successful.
However Microsoft discorage there use because it is not supported. W2K & XP
versions of the “passthru” example found in the DDK’s are supported and
work. All TCP/IP traffic can be diverted through passthru via NDIS. The XP
version is the lastest version of the sample and shows how to accept TCP/IP
traffic. I presume you wish to trap packets from a dial-up connection. On 2K
and XK there are tick boxes on the installed drivers, assuming you use
passthru, that can disable the binding to the network card/dialup adapter,
so I would think that this could be achieved programatically, do not how
though…
Hope this helps

Hi Steve,
Thanks for the information. Actually, we wanted to have some kind
of encapsulation/manipulation on the PPP data received from NDISWAN,
before giving it to the WAN miniport. Also we wanted to have an
option of not having this manipulation in some cases, so we thought
about having a IM for doing this.
Thanks once again.
Regards,
Rajiv.
