Mikrotik VLAN routing

Is it possible to route packets from VLAN?

I’d like make this:
We have one router CCR1036-12G-4S and sip server connected to it. Our clients has RB951-2n. Each has external ip. We’ve made EoIP tunnel for each client. We’ve created VLAN under each EoIP tunnel. I want to make clients be able to connect to sip server, but not to see other clients. How can i make it?
