Please tell me how to properly implement mesh.
router Zyxel Keenetic Giga III
managed PoE switch D-Link DGS-1510-28P /A1A
IP NVR (network card 2)
N is the number of IP cameras
N number of computers
On the router (192.168.1.1 locr) comes to the Internet on WAN, computers and DVR sit on the 1st subnet, all the cameras inside the Registrar sit on the 0th subnet together with a PoE switch and away from the main router.
You need to configure the network so that Cameras and Computers were in their subnets, but the camera had access to the Internet, and I'm from the 1st subnet had access to 0ую.
PS the switch though, and managed, but to engage in the delimitation of networks will not, it only works as a PoE switch, not more.
