NAT Traversal v1.65|NAT Traversal v1.65

 NAT Traversal v1.65 is a game resource pack designed for UNET (Unity Networking) that simplifies peer-to-peer connections. With just three methods—StartHostAll(), ListMatches(), and StartClientAll—developers can implement seamless multiplayer networking without modifying existing UNET code. The solution reduces reliance on expensive relay servers by up to 95%, saving up to 95% in bandwidth costs, with only 5% of connection time requiring relay usage. It enables direct player connections whenever possible, even behind routers, with a fallback to Unity's relay servers if NAT traversal fails, ensuring reliable connectivity. The system automatically switches between direct and relay connections based on availability, providing the best possible connection experience. Players connect faster by bypassing match creation or joining delays. Full support for UNET's Host Migration ensures no game drops when the host leaves. The pack includes a lobby script that perfectly replicates UNET's NetworkLobby functionality, along with example scenes demonstrating NAT Traversal in action, including integration with lobbies, host migration, and the Match Up plugin.
