Setup Help Needed - Create and Route Between VLANs

I am using Unifi wireless APs to create two wireless networks where each AP broadcasts out two SSIDs. There will be a secured wireless network that will be VLAN1 and just be part of my internal network.

The second SSID will be an open network for guests that should be VLAN2.

I want to use a mikrotik 750 to route the traffic between the two VLANs. So, my VLAN1 (secured) network will be 10.10.0.x and my open network will be 192.168.88.x.

I have the Unifi setup figured out (I think) but I have never used router OS before. Could someone give me detailed instructions (step by step) on how to setup my Mikrotik?

I have attached a drawing so hopefully it will fill in any gaps that I might have left out.

One thing is that I don’t want traffic from my secured network to have to go across the mikrotik. I would like just the guest wireless traffic to have to traverse the mikrotik.

Thanks for the help.

on rb 750. U dont tell what ip is for 88.x network. assuming u have 88.1.

10.10.0.253 have to be your gateway for 10.10.0.x network
192.168.88.1 have to be gateway for 192.168.88.x network

then add a default route on 750 to 0.254 (if this is nating) and wolla.. it should work.

After more reading, do I really only need to plug in one physical interface and then just assign vlan1 and vlan2 to it?

I think so.
