Question about origin of packet relative to peer

[nicolas prochazka]

Hello,
Using one wireguard Interface, with multiple peer
How can i know that a packet come from peer X ?
Is is possible to mark packet not a level interface (wg0) but at peer level ?
I can dump packet at wg0 but i lost the peer origin.

Thanks,
Nicolas
