Ubiquiti AmpliFi Instant Router on HAp Lite Capsman

Hi All

Im not great with configs on a mikrotik. what i have setup works well and now i need to add more configs…

I bought a Ubiquiti AmpliFi Instant Router to replace the wireless on the HAp lite in the study.

I have the main MK in the garage and then ethernet to the study where the HAp lite is and then plugged into this HAp lite (managed by capsman) i have the Ubiquiti AmpliFi Instant Router.

I have a DHCP pool on the HAp lite of 192.168.89… but now that the wireless is off on here i want to have the AmpliFi use the pool.

What is the correct setup if i have the AmpliFi plugged in? I can set a VLAN ID as well. I wanted to know what the best way of going abouts this is? and how i would configure it?

Thanks
