Hi Arthur,
you can't get senders MAC address, it is not even present in incoming
packet/datagram. All you can get is MAC address of last switch/router on
the way and the MAC of interface on app server side, which is kind of
useless for you I guess (seems like you want to use this info as an ID).
ONLY way how to do this is include this info in the request send by clients.
