I had try the passthruex part 2, but it not work properly. It doesnt filter<Snip>
IP packet, event when I try testuiocrl to show the filter status, no IP
packet is proccesssed.
Then I try to modify it to filter ARP packet as follow. It can realize
ARP packet, it's fields. But when I try to modify the ARP packet. The
NdisGetReceivedPacket(pAdapt->BindingHandle, MacReceiveContext) doens't
work
well, and I always see "No packet receive!" but the network still work
well
and I can see the PtReceivePacket never work. What happens here???
The following is my code. In this FltFilterReceive, I modified to only
filt
ARP packet, and I sure it work well. I test the driver in the ethernet
connection with router modem ADSL, the ARP packet of that modem, always
add
18 byte as data of ARP packet. I try to modify this packet by strip this
18
bytes, only ARP header is encapsulate.
NEVER assume that NdisGetReceivePacket will return a packet. There are
several legitimate situations where no packet will be fetched.
Instead, base your implementation on fetching the packet data from the
HeaderBuffer and LookaheadBuffer.
