I am using Passthru to implement NAT. The driver runs
well with two ethernet NICs. If I dont start NAT packet
tranlsation, The driver still runs well with one LAN adapter
and one wan adapter.
But when I start NAT packet translation,After some packets
(always 2 to 4 packets) which comes from LAN adapter are
translated and sended by wan adapter, there is a kernel
bug check occurred. I only tried to translate icmp echo request/reply
 packet.
Softice tell me:
   kebugcheckex: bugcheckcode=0xD2 p1=....p2=..,p3=..,p4=..
I could not find what 0xD2 means because it is not list in the
windbg references.
Here is the code I used to redirect the packet:
***********************************************
//translate packet from LAN and send via WAN.
  if(pAdapt->IsLocal)
  {
         if(!TranslateLocalICMPPacket(
                    pAdapt,
                    pEthHeader,
                    iphdr,
                    icmphdr)) break;
          //send packet via global adapter
         if (pAdaptList->IsLocal)
        {        
              pAdaptSend = pAdaptList->Next;
        } else
        {     pAdaptSend = pAdaptList; }
        NdisSend(&Status, pAdaptSend->BindingHandle,    Packet);
  }
//translate packet from WAN and send via LAN
if(!TranslateGlobalICMPPacket(
               pAdapt,
               pEthHeader,
               iphdr,
  icmphdr)) break;
//send packet via local adapter
if (pAdaptList->IsLocal)
{
   pAdaptSend = pAdaptList;
}
else
{
   pAdaptSend = pAdaptList->Next;
}
NdisSend(&Status,
pAdaptSend->BindingHandle,
 Packet);
*************************************************
I read DDK document about NDISWAN. Should I queue the packet
and then send it?
Please give me suggestion:)))
Thanks
yours brucie

Are you using the latest debugger from
http://www.microsoft.com/ddk/debugging?
If so then try the command !analyzebugcheck and see what help it can give
you about the crash.
