Could you build this?
No Implementing robust, multi-network NAT traversal requires deep specialized networking knowledge across STUN, TURN, ICE, UPnP, PCP, and various router NAT mapping and filtering behaviors.
What it would actually take: The stack involves low-level Python socket programming, raw UDP packet handling, and asynchronous network loops (asyncio). The complex part is handling the taxonomy of symmetric NATs, carrier-grade NATs (CGNAT), dual-stack IPv4/IPv6 edge cases, and deterministic port-prediction hole-punching algorithms with custom fallback relaying.
