Why is there no Internet access Mikrotik virtual ap?

Question

Mikrotik

Good afternoon. There is Mikrotik hAP lite, the task was to set up a guest wi-fi grid.
What we have:
Local network 10.0.3.1/24, Mikrotik receives settings via dhcp, configured in bridge mode (not router), all interfaces are connected to one bridge. I did it according to the manual from wiki.mikrotik.com/wiki/Russian/Simple_Access_Point , in the setting, instead of ether1, I specified bridge (because ether cannot be specified). As a result, the guest network is detected, connected, receives settings via dhcp, hung on virtual ap, but there is no access to the Internet.
In Firewall it is written

Tell me, please, in which direction to dig? It seems like a childish question, I shoveled a bunch of information, but I did not find a solution. Thank you!

Answer 1

I'll try to guess, because you did not lay out settings: Gateway is not registered in DHCP on Virtual AP? Or DNS? Is masquerading necessary here? Maybe your network configuration will have enough routing?

Answer 2

To begin with, there is little information, is Virtual AP also in the bridge ?? Show the dhcp settings on the guest network.
