DHCP Server sending to fortigate in branch factory

Hi Everyone,

My name is nugraha this first time i'm using fotigate , i have a question, in my branch factory i want to every user connect to wireless network receive ip dhcp from factory center ,whether it can be done so that wireless-connected branch factories get ip dhcp from the central factory?

My topology Factory center -> Branch factory (link using fiber optic and i have connected with factory center with tunnel )

Thanks
