I think the machine is requesting the router a new IP and the router
couldn't match the MAC of the request with the MAC associated to the
reserved IP 192.168.10.2, so is giving a new IP in the range. Something
change at the machine, did you check the MAC AE:5D:BA:91:67:2D against your
rule in the router?
