Cannot access Vlan

Hey, I am new here. I just started my experience with Mikrotik, before I was using only Cisco…

I am trying to add new vlan20 for my guest users ( at home), I am using Ubiquity toughtswitch and Ubiquity AP. I created IP pool,DHCP, vlan20 and associated with eth port. On the switch I added vlan 20 to the trunk, and created SSID with vlan20, but… I am getting correct IP address from vlan 20 pool but nothing more I cannot go see any other devices. When I look on interfaces tab I can see only see RX, it look like one way traffic.
Do I need to add any Firewall rule ?

anyone?
