Landscape - Linux Router Configuration Tool

Landscape Router is a tool developed using eBPF / Rust / Vue that helps you configure Linux as a router.

Overview

Core Features

• Traffic Shaping: Entry: (SIP-CIDR, MAC), Traffic target: (DIP, Domain, Geo matching rules)
• eBPF Routing
• Independent DNS configuration and caching for each Flow (avoid DNS pollution and leaks)
• Traffic routing to Docker containers
• Geo database management

Main Features

✅ Implemented and tested ⚠ Feasible but not tested ❌ Not implemented

• IP Configuration
  • Static IP Configuration
    • ✅ Specify IP
    • ✅ Configure gateway with default route
  • DHCP Client
    • ✅ Specify host name
    • ❌ Custom options
  • PPPoE (PPPD version)
    • ✅ Default route specification
    • ⚠ Multi-WAN dial
    • ✅ Network interface name specification
  • PPPoE (eBPF version)
    • ✅ Protocol implementation
    • ❌ Packet size exceeding MTU due to NIC GRO/GSO (unresolved)
  • DHCP Server
    • ✅ Provides simple IP address allocation and renewal service
    • ✅ Customizable gateway and network segment access configuration for allocated IPs
    • ✅ MAC address and IP binding
    • ✅ IP allocation display
  • IPv6 Support
    • ✅ Use DHCPv6-PD to request prefixes from upstream routers
    • ✅ Use RA to advertise multiple prefixes to downstream devices
• Traffic Shaping Module
  • ✅ Support for traffic differentiation using IP/MAC values
  • ✅ Independent DNS configuration and caching for each flow
  • ✅ Route marked traffic according to marking configuration (direct/discard/port reuse allowed/redirect to Docker container or network interface)
  • ❌ Set tracking marks for specified data
  • ✅ External IP behavior control based on marked rules, with support for using geoip.dat for configuration
  • ✅ Conflict resolution between IP rules and DNS rules based on priority (lower values have higher priority)
• Geo Database Management
  • ✅ Multi-source geo database management
  • ✅ Automatic IP/Site updates
• DNS
  • ✅ Support for DNS over HTTPS, DNS over TLS, and DNS over QUIC upstream requests
  • ✅ Support for specifying specific upstream DNS for specific domains
  • ✅ DNS hijacking (return A/AAAA resolution)
  • ❌ DNS hijacking returning multiple records (e.g., TXT/CNAME or others)
  • ✅ IP marking for specified DNS resolution results for processing by marking modules
  • ✅ GeoSite file support
  • ❌ Support for Docker container domain labels in DNS resolution
  • ✅ Support for test domain queries
• NAT (eBPF) Implementation
  • ✅ Basic NAT
  • ✅ Static mapping / Open specified ports
  • ✅ NAT defaults to blocking port reuse, dynamically allowing port reuse for opened IPs based on marking module configuration
• Metrics Module
  • ✅ Periodic reporting every 5s of connection information (bytes/packet count)
  • ✅ Display current connections (not yet combined with NAT connection information)
  • ❌ Open metrics export API
• Docker
  • ✅ Support for simple Docker container operation and management
  • ⚠ Image pulling
  • ✅ Route traffic to Docker containers running TProxy
• WiFi
  • ✅ Use iw commands to switch wireless network interface status
  • ✅ Use hostapd to create WiFi hotspots
  • ❌ Connect to WiFi hotspots
• Storage
  • ✅ Use database instead of current configuration storage
  • ✅ Export all current configurations to landscape_init.toml file
  • ❌ UI provides configuration upload and restore component
  • ❌ Add configuration modification component
  • ❌ Separate database address specification for metrics
• Miscellaneous
  • ✅ Login interface
  • ❌ Add English frontend pages
  • ✅ Network interface XPS/RPS optimization, load balancing across cores to improve overall throughput, but interrupt binding is not well understood - suggestions welcome in issues
