Hello, I am trying to develop ndis filter driver working as NAT driver. I want to change destination address.
Here is my method to do it.
I referenced "https://community.osr.com/discussion/255174/how-to-send-cloned-nbls" to free the cloned NBL in FilterSendNetBufferListsComplete.
However, I built it and install at VM, but its internet access cut off.
So for testing, I wrote same destination ip addresses as original NBL in cloned NBL, by same methods above, and it worked normally.
So is it a problem with the one ip address that I arbitrarily overwrite? Or is it an ip checksum problem? or else?
I don't know because there is too little information to find.
After struggling a few weeks, I think I am close to what I want to make... but this problem is blocking me from progression.
