Route back to wifi controller

Purpose of this setup  is for unsecure wireless devices to be sent to VLAN 50 192.168.50.0 network.

I need to be able to route back to 10.0.0.0/24 from 192.168.50.0/24 network. There is a Cisco ASA 5510 configured for the 10.0.0.0/24 network. Switches have been configured with VLAN 50 192.168.50.0/24 tagged and all can be pinged.

Here is the basic flow.

Fortigate  v5.4 interface mode, Ubiquiti Unifi Wifi AP’s

AP’s are on the 10.0.0.0/24 network, Unifi controller has 10.0.0.201 address.

Fortigate Port 1 LAN has 192.168.30.1 address and VLAN 50 has 192.168.50.1 address.

3 networks – 10.0.0.0/24, 192.168.50.0/24 & 192.168.30.0/34

STEPS Wireless device gets on the network where Unifi controller puts it on VLAN 50 192.168.50.0/24. Yes  Fortigate assigns IP address to device? Yes Wireless device needs a voucher from Unifi controller on 10.0.0.201 Fortigate routes to 10.0.0.0/24 network? NO
