How to connect to a different subnet based on the wireless ssid and not the interface

Hello,

I would like to know if the following setup is possible, and if it is, how to do it.

Here is the situation:

2 interfaces with 2 subnets.

• ETH1 -> 192.168.1.X
• ETH2 -> 192.168.2.X

2 AP:

1. APX -> CONNECTED TO ETH1
2. APY -> CONNECTED TO ETH2

With the UNIFI CONTROLLER i seted up 2 wireless networks, WIFI_PRIVATE and WIFI_GUEST.

Bouth ACCESS POINTS broadcast this 2 wireless networks and users can connect fine.

Can i make a setup so when an user connect to WIFI_PRIVATE it uses the DNS server from ETH1 (192.168.1.x) even tho it connected through APY?

Diagram to make it easier attached.
