I was trying to manipulate SOME/IP messages by falsifying their content(Payload) sent between 2 ECUs at run time.

After setting up the Hardware VN6510A MAC Bypassing and integrating it in the data traffic path between those 2 ECUs to monitor and control all Ethernet data streams.

ECU A ---> eth1 interface --VN6510A-- eth2 interface ---> ECU B

I successfully catch our target SOME/IP messages and I also succefully manipulate their paylod. But at the end we got 2 SOME/IP messages: the real coming message and the falsified message forwarded at the same time.

How could we bound those 2 SOME/IP messages, the real message and the falsified message together, so that we could have just one falsified SOME/IP message, knowing that I am using the same SOME/IP message handle.

I used the callback function void OnEthPacket(LONG channel, LONG dir, LONG packet) to register a received Ethernet packet.

Probably by setting your VN.... to "Direct" and not "MAC Bypassing"

Well we could not manipulate Messages at run time using the vector box VN6510A Solution because simply their box doesn't support this feature.
