NAT Traversal / Hole Punching

The technique of establishing direct peer-to-peer connections between nodes behind NATs/firewalls (e.g. via QUIC hole punching as in iroh), the connection-layer enabler for serverless inference meshes.

grounded in: Trend NOTABLE: 'Mesh LLM: Distributed AI inference running peer-to-peer over the iroh networking stack' — iroh's core capability is QUIC-based hole-punched direct connections.
