My goal is to separate the network into vlans for Iot devices, cameras, wifi devices and lan. Currently have a home network setup with 3 A1900 Asus routers configured as a mesh network with a cat5e ethernet backhaul. Switches are a TP Link 16 port gigabit unmanaged switch and a BV Tech 8 port 150W unmanaged switch with uplink port. I've got 2 NICs in the BI machine and cameras are on their own Lan. I setup the router with a VPN server so I can VPN into the network when I'm away from home and view the cameras. There are no ports open on the router (80 and 443) so to speak. Everything is running very well but I'm concerned about the Iot devices. I thought about purchasing a used 24 port Cisco/HP/Dell off ebay which is where I could use a recommendation. Also thought about maybe migrating the network to Ubiquiti products but that would be rather expensive given what I currently have invested. Maybe I'm just over thinking things and should leave well enough alone. Your thoughts? Thanks.
