   This is due to VPN on layer2 usually doesn't receive MAC addresses.
   You can try modifying the code as below for line 57:

   
     if args.mac is None:
               self.macaddr = '00:00:00:00:00:00'
           else:
               self.macaddr = args.mac

   Try to run the python directly instead for example for me was sudo python3 /opt/mitm6/mitm6/mitm6.py -d <domian> -i tun0
