SteamBridge is a Layer 3 virtual network that routes IP packets over the Steam P2P network using TUN kernel interfaces on Linux and Windows. A hand-written C++ bridge to the Steam transport is loaded from Go without cgo, and a custom IPAM protocol assigns adapter addresses automatically to create a zero-configuration secure Virtual Private LAN. A Wails/Next.js dashboard shows live peer status, exposes runtime firewall controls, and joins Steam friends directly.
