I'm looking at the passthru NDIS Intermediate driver example, and would like to extend this sample to a very simple packet filter.

The filter should be able to block/stop all packets to port 4000.

How should passthru be extende to fit this purpose.

Thanks.

The PCAUSA NDIS Intermediate toolkit is an excellent resource and well worth what it costs.

When i compile passthru and install it it seems to initilize, but it does not receive packets. Should i do something from a user application for this to happen?
