Zyxel AP NAT mode is a network setting on Zyxel access points where the AP itself acts as a DHCP server and NAT (Network Address Translation) device. This mode creates an isolated network for wireless clients. Client cannot communicate with other clients associated with different AP.

NAT mode is used to have the AP create a DHCP subnet with its own NAT for the SSID. Provide minimum hardware requirement for Wi-Fi of small shop/café
If AP management IP address is NOT part of “10.0.0.0/8”, SSID subnet becomes “10.0.0.0/8”.
If AP management IP address is part of “10.0.0.0/8”, SSID subnet becomes “172.16.0.0/12”

Go to Configure > Access points> SSID settings. Add to SSID as "Wi-Fi". Then click "Edit".
