Re: FortiClient for VPN Question / Licensing
I just went through this with my Fortigates.
As I understand it, the initial free 10 clients are for forticlients that you manage from the fortigate. The clients register to the 'gate and you can set different options for them (AV, Web Filter, App Control), enforce compliance, etc.
If you don't plan on using the 'gate to manage the clients, you can connect as many clients as you want (up to the box's capacity, of course.)
So it's "free" for basic RA connectivity, licensed if you want the cool bells & whistles that come with the ability to manage the clients.
