ESP32 NAT Router
Firmware that turns an ESP32 microcontroller into a WiFi NAT router with firewall ACLs, WireGuard VPN, DHCP, port forwarding, packet capture, and WPA2-Enterprise support. Includes a beta MCP server bridge that allows AI assistants to control the router's network operations.
Best When
You want an inexpensive, hackable WiFi router with AI control capabilities for lab, IoT, or home network experimentation.
Avoid When
You need production-grade networking, high throughput, or a purely software-based MCP server without hardware dependencies.
Use Cases
- • Extending WiFi range with a cheap ESP32 as a NAT bridge
- • Creating an AI-controlled network firewall and router for lab environments
- • Setting up WireGuard VPN tunnels on embedded hardware
- • Live packet capture streamed to Wireshark for network debugging
Not For
- • Production or high-throughput networking (limited to ~15 Mbps, 8 clients max)
- • Enterprise-grade firewall deployments
- • Users without ESP32 hardware and flashing capability
- • Software-only MCP server use cases (requires physical hardware)
