## Universal Network, Workspace & Enterprise Governance

### 1. Mesh VPN & Public WAN Architecture
- **Strictly Public WAN Routing**: NullPort operates exclusively over the public internet, eliminating lateral internal LAN/RFC 1918 security risks.
- **Relay Default with Dynamic 8 MB/s P2P Shift**: Traffic routes through WAN relay by default, automatically shifting to public UDP P2P reflexive paths when throughput exceeds 8 MB/s (8,388,608 bytes/sec), returning gracefully to relay when bandwidth subsides.
- **Layer 2 / Layer 3 Mesh VPN**: Wintun (Windows) and utun (macOS/Linux) virtual private networking for isolated multi-device clusters.
- **Secondary Network & Wi-Fi Pass-Through**: Share dedicated secondary Wi-Fi or Ethernet adapters for isolated wireless testbenches.
