Ī similar basic NAT feature for the ESP32 can be found at. If you are looking for a way to integrate the NAT feature into your Arduino project - see. For a setup with multiple routers in a mesh to cover a larger area a new mode 'Automesh' has been included. It also includes support for a packet filtering firewall with ACLs, port mapping, traffic shaping, hooks for remote monitoring (or packet sniffing), an MQTT management interface, simple GPIO interaction, and power management. This is an implementation of a WiFi NAT router on the esp8266 and esp8285.
