helloooo everyone,
i have this new problem that has been begin two days ago and till now:
mikrotik gives dhcp leases to users that not on net, and the used mac address is the mac address of my access point.
the situation is very weard, never happend to me b4, and i asked and the same problem exist in more than 3 people.
the leases keep giving ip addresses till the pool is full and no address can be given no more
i wonder if anyone here knows where the problem is??? 
i have only 50 users on this mikrotik, the ip pool is 192.168.0.2-192.168.0.254
i use hotspot server with http-chat login method, access point filter mac’s
omny standard 2w amp. sinao access point, static config. ip: 192.168.1.1 subnet: 255.255.255.0, gateway:0.0.0.0 .
