ISP Onu Wifi-Router and RB750 in same subnet

Hi,

My ISP gives me a Fiberhome ONU Wifi router, I have a RB750 which I want to use as gateway from my network, but my wireless clients will connect on ONU Router, so, how can I use both (ONU and RB750) in the same subnet and aply controls on Wifi clients.

For example:
ONU Ip 192.168.1.1
RB Ip 192.168.1.2

DHCP 192.168.1.3-192.168.1.100

Questions:

Gateway have to be ONU or RB?
Did I have to use Nat Masquerade betwin routers?

Does anyone have any ideas :question:

This is not possible. But you can set the RB750 in bridge mode and use it as an extra access point.
