In this video, I'll walk you through briefly how to create a segregated separate VLAN for your guests with its own DHCP server, access rules, bandwidth limitations, and more on my Fortinet Fortigate 60E which is the same process for a fortinet 80E etc.
I also show you how to integrate that functionality with your Ubiquiti access points/switches through my cloud key gen 2+ and the unifi controller
VLANs are very useful for outside traffic and IOT devices.
This is a very basic tutorial intended just for education. proceed at your own risk, BACK UP YOUR CONFIGS before you touch either system and if you damage something, you're on your own.
Hope this helps!
