Description

ESP32 NAT Router firmware enables the ESP32 device to function as a WiFi NAT router, routing between AP and uplink interfaces such as STA or Ethernet. It supports VPN tunneling via WireGuard, DHCP reservations, firewall rules, port forwarding, and live packet capture. Additional features include a web interface, serial and remote consoles, LED and OLED status indicators, MQTT telemetry for Home Assistant, and experimental AI control via the Model Context Protocol (MCP). This makes it suitable for network extension, guest networks, VPN routing, and IoT network monitoring.
