        May it makes sense for you to read IPSec documents regarding this subject? WinpkFilter gives you raw access to packet data, so you can do anything described in IPSec specs.

            Just parse IP header of the packet and format the string with IP address…

                When implementing IPSec you need to insert additional headers (AH, ESP) or even incapsulate packets, thats why you need to decrement MTU used by system.

                  do i need to set MTU if i want to add additional data to the original packet Data?
                  Like
                  Packet org. Data=”asdasdasdasda”
                  I would like to replace it with Data=”###asdasdasdasda###”
                  Thank u
