Features

• NAT Routers - Functions as a wireless repeater or NAT router to extend WiFi coverage using an ESP32.
• WiFi Range Extenders - Functions as a WiFi range extender to increase wireless coverage by repeating an existing signal.
• NAT Subnetting - Creates a private secondary subnet using Network Address Translation to connect clients to an upstream network.
• Network Routing - Acts as a network router for IoT devices with port forwarding, access control lists, and bitrate limiting.
• Transparent Layer 2 Bridges - Implements a transparent layer-2 bridge to forward Ethernet frames between wireless interfaces for shared subnets.
• Wireless Bridges - Implements a layer-2 bridge that forwards Ethernet frames between wireless interfaces for shared subnets.
• Enterprise to PSK Converters - Translates PEAP-authenticated enterprise networks into WPA2-PSK networks for incompatible devices.
• Enterprise to PSK Translation - Translates PEAP-authenticated enterprise networks into WPA2-PSK networks for devices lacking enterprise support.
• Enterprise WiFi Translation - Translates PEAP-authenticated enterprise networks into WPA2-PSK networks for devices that lack enterprise authentication support.
• Network Address Translation - Functions as a NAT router that creates a private secondary subnet to connect clients to an upstream network.
• Token Bucket Throttlers - Regulates network bitrate for connected clients using a token bucket throttling algorithm.
• Ethernet Interface Configuration - Supports SPI-connected network interface controllers to provide a stable wired uplink.
• Over-the-Air Device Updates - Supports over-the-air firmware updates by downloading and switching binary versions via HTTP.
• Serial Command Line Interfaces - Provides a serial or TCP-based command line interface for configuring network routing and system settings.
• MQTT Clients - Uses an MQTT client to publish device metrics and receive remote network configuration commands.
• DHCP Snooping - Implements DHCP transaction snooping to automatically map client MAC addresses to their assigned IP addresses.
• Forwarding Databases - Tracks IP-to-MAC mappings and removes stale entries using a time-to-live expiration mechanism.
• Mesh Network Coordinators - Coordinates multiple repeaters to optimize uplink selection and synchronize SSIDs for multi-hop coverage.
• Multicast DNS Resolution - Provides mDNS proxying to relay multicast DNS queries and responses for local hostname resolution.
• Network Bitrate Limiting - Implements bandwidth capping for connected clients using a token bucket algorithm to regulate upstream and downstream bitrates.
• Network Traffic Captures - Streams internal network traffic in pcap format to a TCP port for real-time external analysis.
• Port Forwarding - Maps specific external ports to internal IP addresses and ports to expose internal services.
• Web-Based System Configuration Interfaces - Includes a browser-based graphical interface for managing wireless parameters and system configuration.
• IP Allow/Deny Lists - Defines protocol rules to allow or deny traffic based on source and destination IP addresses.
• Network Traffic Analysis - Provides network traffic analysis by mirroring internal traffic in pcap format to a TCP port.
• PCAP File Exports - Streams internal network traffic in PCAP format to a TCP port for real-time external analysis.
• Real-Time Traffic Mirroring - Duplicates internal network packets and streams them over TCP in pcap format for real-time external analysis.
• Remote Device Management - Enables remote device management via MQTT status publishing and web-based configuration interfaces.
