 - **Rust Engine** handles all networking: TCP, UDP, TLS, QUIC, HTTP proxying, connection management, security, and metrics
 - **TypeScript** provides the npm API, configuration types, route helpers, validation, and handler callbacks
+- **NFTables** managed by [`@push.rocks/smartnftables`](https://code.foss.global/push.rocks/smartnftables) — kernel-level DNAT/SNAT forwarding, firewall rules, and rate limiting via the `nft` CLI
 - **IPC** — The TypeScript wrapper uses JSON commands/events over stdin/stdout to communicate with the Rust binary
 - **Socket/Datagram Relay** — Unix domain socket servers for routes requiring TypeScript-side handling (socket handlers, datagram handlers, dynamic host/port functions)
