Fortigate + AP + iPhone

Hello,

We use some FGT900 with 5.2.9 release, attached AP 221C, with two SSID, one bridged on the Fortigate and the other one in WPA2 Personal bridged on the AP and using customer internal DHCP Server. Everything work nice with Windows Laptop and Android msartphoen, but with the MacBook and the iPhone device we see that he device attach to the SSID but don't receive any IP address from the DHCP. The DHCP are wrking nice since I deliver the IPs address fr all the networkA. Any idea ?
