Struct NatProbeResponse 

pub struct NatProbeResponse {
    pub inner_ip_id: u16,
    pub inner_udp_checksum: u16,
    pub responder_addr: SocketAddr,
    pub response_ip_id: u16,
    pub received_at: Instant,
    pub icmp_type: u8,
    pub icmp_code: u8,
}

Response from a NAT probe.

Fields

inner_ip_id: u16

IP ID from the response (in ICMP inner packet).

inner_udp_checksum: u16

UDP checksum from the response (in ICMP inner packet).

responder_addr: SocketAddr

Source IP of the ICMP response (the responding hop).

response_ip_id: u16

Response IP ID (for NAT loop detection).

received_at: Instant

Time received.

icmp_type: u8

ICMP type (11 = TTL exceeded, 3 = unreachable).

icmp_code: u8

ICMP code.

Implementations

impl NatProbeResponse

pub fn nat_id(&self, original_checksum: u16) -> NatId

Calculate NAT ID by comparing with original probe.

pub fn rtt(&self, sent_at: Instant) -> Duration

Calculate RTT from probe send time.

pub fn is_ttl_exceeded(&self) -> bool

Check if this is a TTL exceeded response.

pub fn is_destination(&self) -> bool

Check if this is the final destination (port unreachable).
