Hotspot + traffic forwarding

Good afternoon.
Faced with the problem on mikrotike (hAP lite v6.29.1), set up access to the Internet + dhcp + nat, etc. Everything works fine, but it took yesterday to stick with advertising hotspot.
Prior to this adjustment had a positive experience with this native hotspot software. Redirect to the page takes place and an Internet only works when I’m sniffering bridge interface.
Otherwise the net does not work, similar to the situation with the wrong frame size of the exposed on the network interface.

Any ideas?
