RB750 and vlan

Hi,

I've tried to setup vlan on RB750 and dlink switch DES-1100-16. So I've created vlan 2 on switch and router. On router vlan interface is ether5, on switch port 2 is untagged and port 16 is tagged and connected to mikrotik on ether 5. I've created secondary dhcp on vlan interface. When I connect computer to port 2 on dlink I've got ip address from mikrotik, but can't ping gateway nor internet. If I connect to mikrotik port 2-4 everything works fine. Pls advice. Here is my config:
