}

Comprehensive NAT information about the local network.

Contains details about NAT type, public/private addresses, and port mappings discovered through STUN and other NAT traversal techniques.

Fields

• nat_type - The detected NAT type (Cone or Symmetric)
• public_ips - List of public IPv4 addresses
• public_udp_ports - Public ports mapped for UDP
• local_ipv4 - Primary local IPv4 address
• ipv6 - Public IPv6 address if available

Fields

nat_type: NatType

nat type of the network

public_ips: Vec<Ipv4Addr>

the set of public Ipv4

public_udp_ports: Vec<u16>

the set of public ports mapped from the nat

mapping_tcp_addr: Vec<SocketAddr>

the set of mapped addresses where TCP serves on

mapping_udp_addr: Vec<SocketAddr>

the set of mapped addresses where UDP serves on

public_port_range: u16

The predicted range of public ports, it is used when the nat_type is symmetric

local_ipv4: Ipv4Addr

local IP address

local_ipv4s: Vec<Ipv4Addr>

ipv6: Option<Ipv6Addr>

The public IPv6 address

local_udp_ports: Vec<u16>

The local ports where the UDP services bind

local_tcp_port: u16

The local ports where the TCP services bind

public_tcp_port: u16

The public port of TCP service, which works when there is either nat1 or no nat exists
