//! Packet-level network address translation.
//!
//! Two top-level types:
//!
//! - [`Nat`] — IPv4 NAT between an inside (private) and outside (public) L3
//!   network. Implements both [`L3Device`](crate::L3Device) (as the outside
//!   edge) and [`L3Connector`](crate::L3Connector) (for namespace-isolated
//!   inside attachments).
//! - [`Nat64`] — RFC 6146 stateful translation between an IPv6 inside and an
//!   IPv4 outside, using IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`).
//!
//! Optional pieces:
//!
//! - [`Defragger`] — IPv4 reassembly, enabled per-NAT via
//!   [`Nat::enable_defrag`].
//! - ALGs: [`FtpHelper`], [`TftpHelper`], [`IrcHelper`], [`SipHelper`],
//!   [`H323Helper`], [`PptpHelper`].
//! - [`UPnPHelper`] / [`UPnPConfig`] — SSDP discovery plus a SOAP control
//!   handler ([`UPnPHelper::handle_soap`] returning [`SoapResult`]). The
//!   control port is terminated with the in-tree `vtcp` engine and a minimal
//!   one-shot HTTP/1.1 server; pipelined / chunked requests are not handled
//!   (see `TODO(nat)` in `upnp.rs`).
