Enable Guest AP in AP Mode?

Hi,

Would like to ask if possible to enable Guest AP when the router in AP mode? My setup is this:

GL-AR750S - Main router (router Mode) Guest AP enabled
Connected devices are the following:
GL-AR300M (AP mode)
GL-MT300N-V2 (AP mode)

What im thinking is to create a trunk port to pass different vlans.

Any ideas or help would be great.

In AP mode, the router does not assign IP to the client. I think you only need to configure the client with static IP, such as 192.168.9.2.
