Oh you're very funny and helpfull.
I read all posts and all say for VID and PID, and i got this question if it was possible.
No possible ok, i install it on a USB Key.
I set SN,mac1,VID&PID (correct), but when reboot Xpenology don't ask for IP to DHCP (DHCP is configured well).
I'll try with a new USB key.
