SD-WAN & exclusive ISP WAN

Hi everyone,

So... i've just configured an SDWAN interface with 2 ISP...however, i have another link coming from a third ISP and i want to use that one for wifi traffic.

I've tried to config some sdwan rules but still..everything goes through the sdwan interface (ISP 1-2-3). I was wondering if i could use a vdom for my 3rd WAN and have the first 2WAN in the SDWAN. thing is that all my FAPs are created in the vdom root and if i want to use another ssid or FAP i have to create or register them in the new vdom :S

Has anyone know how to make this config?.

Thanks in advance.
