OPNsense Config Faker

A flexible Rust CLI tool for generating realistic network configuration test data specifically designed for OPNsense testing environments.

What is OPNsense Config Faker?

OPNsense Config Faker is a specialized tool that creates valid OPNsense config.xml files with realistic faked data. It’s designed for network administrators, security professionals, and testing teams who need comprehensive test configurations for OPNsense firewalls.

Key Features

  • OPNsense-Specific: Generates valid OPNsense XML configurations
  • Realistic Data: Creates RFC-compliant network configurations that mirror real-world deployments
  • Multiple Formats: Supports XML, CSV, and JSON output formats
  • High Performance: Built in Rust for fast generation of large configuration sets
  • Offline-First: No external dependencies or telemetry
  • Cross-Platform: Works on macOS, Windows, and Linux

What You Can Generate

  • VLAN Configurations: IEEE 802.1Q compliant VLAN setups
  • Interface Configurations: Physical and virtual network interfaces
  • Firewall Rules: Realistic security policies and access controls
  • DHCP Settings: Dynamic host configuration protocols
  • NAT Rules: Network address translation configurations
  • Routing Tables: Static and dynamic routing configurations
  • CARP VIPs: Common Address Redundancy Protocol virtual IPs
  • RADIUS Users: Authentication and authorization data

Use Cases

  • Testing Environments: Generate test data for OPNsense deployments
  • Security Testing: Create realistic configurations for security tool validation
  • Development: Provide sample data for OPNsense plugin development
  • Training: Generate examples for network administration training
  • Documentation: Create sample configurations for documentation

Quick Example

# Generate 25 VLAN configurations
cargo run --release -- generate vlan --count 25 --output vlans.xml

# Generate firewall rules with VLANs
cargo run --release -- generate --count 10 --format xml --include-firewall-rules
