External Captive Portal and Apple CNA

[mok]

Hi all, I've a fotigate configured for make an external authentication with external captive portal. I've attached a third part AP in the DMZ port. Everything work as expected but in the apple devices I haven't got the CNA (push captive portal), but I must search something URL in the browser for see my captive portal. Someone have an idea for this?

Thanks !

Hi Baptiste, what you say is exactly that i don't want. I would like the CNA, I see in this old video https://www.youtube.com/watch?v=cSKCXO1YuPU at min 4 that the MAC OSX push the captive portal. In this video he used the internal captive portal with inside controller. 

If I used an external AP without the fortigate controller, I can't see the CNA.
