It's work yet but it's not really what I want.
I want that the pc 1 have a address like : 172.168.x.x
And pc 2 have : 10.0.x.x.
It's a example I try to connect 2 devices without the same "address" "network"
Don't know if you understand what I mean.
The test work when the 2 PC have the same network like 192.168.1.10 and 192.168.1.20
