Is it Required to Open Ports to Allow Access Point to Broadcast on WAN?

Hi there,

I have two Access Points on my LAN network. I have a FortiGate 200E firewall located at a different building, maybe fifteen miles away from my LAN network. For testing I have installed two AP's on my LAN network, and also installed software to manage AP's. Both AP's are broadcasting and working on LAN.

I've decided to have a central location to manage AP's. That location is fifteen miles away from LAN and I'm able to remote into WAN computers and servers. WAN location has a FortiGate 200E firewall. We have VPN working, I can ping network computers. Communication between LAN and WAN is working great, and we have no complaints.

I've uninstalled AP software and did a factory reset on the AP's. I know for a fact, the two AP's are broadcasting and waiting to be connected via its software. 

On the WAN network, I decided to install AP software on a workstation. After successfully installing software, I noticed AP's aren't being detected, which means AP's are not broadcasting pass my LAN network. On the FortiGate firewall, do I need to create a new policy and open ports TCP 8080, 8443, 8843, 27117  and UDP 3478 to allow AP's to broadcast on the WAN network?

Both AP's are connected to the network and are ready to be configured. I attached an image of my network setup.
