Firmware for the ESP8266/ESP8285 that turns the chip into a full WiFi NAT router and, in a separate edition, a true L2-bridge WiFi repeater. It includes a firewall with ACLs, port mapping, traffic shaping, remote monitoring/packet sniffing hooks, MQTT management, GPIO control, and an Automesh mode for multi-router coverage.

Use cases

• extend the range of my home wifi network
• set up a guest wifi network with a different password
• create an isolated secure network for IoT devices
• convert a WPA2 Enterprise network to WPA-PSK
• monitor and sniff wifi traffic with wireshark
• build a battery-powered outdoor mesh network
• experiment with routes, ACLs and traffic shaping on a cheap device

When to choose

• you have an ESP8266/ESP8285 board and need a low-cost NAT router or range extender
• you want firewall ACLs, port mapping, or traffic shaping on a tiny embedded router
• you need an IoT device network segment with MQTT-based management
• you want a WiFi probe/monitor for traffic analysis

When to avoid

• you need high throughput beyond ~5 Mbps
• you have an ESP32 - use the esp32_nat_router project instead
• you want to integrate NAT into an Arduino sketch - use lwip_nat_arduino instead
• you need a modern maintained router platform rather than ESP8266-era hardware limits
