ipnat

i want to write a filter in the network stack. Ideally my filter should
attach itself to ipnat but below it (as a lower filter). I am new to network
drivers, and have no idea whether this is possible or not.

Is there a sample that can help me.

Any NDIS IM will do. IPNAT is not an NDIS IM, it is a plugin to TCPIP
itself.

According to my knowledge IPNAT driver is tightly attached with TCPIP driver
and TCPIP driver send packet to this driver. IPNAT driver sends packet back
to TCPIP driver.

Windows IPFtilter driver allows to hook itself but i didnt found anything
directly to hook IPNAT. Many place i read this can be done outside the TCPIP
stack i.e at NDIS level.

Thanks
