Struct NatClassification 

pub struct NatClassification {
    pub nat_type: &'static str,
    pub public_ip: Option<IpAddr>,
    pub observations: Vec<StunObservation>,
    pub queried: u32,
    pub succeeded: u32,
}

Result of NAT classification.

nat_type interpretation:

• "cone" — all responding servers reported the SAME public port → the NAT uses a single mapping per source socket regardless of destination. punch will work to any peer.
• "symmetric" — responding servers reported DIFFERENT public ports → the NAT allocates a fresh public port per destination. punch will FAIL because the port the peer punches at (learned from one STUN server) won’t be the port your traffic to them uses. Requires a TURN relay to recover.
• "unknown" — fewer than 2 servers responded → can’t classify; don’t draw conclusions.
