Field Detail

### publicAddress

    public final InetAddress publicAddress

### natType

    public final short natType

### mtu

    public int mtu

  The MTU as advertized by the JVM

### NOT_SUPPORTED

    public static final short NOT_SUPPORTED

  The plugin does not support detecting the NAT type.

    Constant Field Values

### FULL_INTERNET

    public static final short FULL_INTERNET

  Full internet access!

  See Also:
    Constant Field Values

### FULL_CONE_NAT

    public static final short FULL_CONE_NAT

  Full cone NAT. Once we have sent a packet out on a port, any node anywhere can send us a packet on that port. The nicest option, but very rare unfortunately.

  See Also:
    Constant Field Values

### RESTRICTED_CONE_NAT

    public static final short RESTRICTED_CONE_NAT

  Restricted cone NAT. Once we have sent a packet out to a specific IP, it can send us packets on the port we just used.

  See Also:
    Constant Field Values

### PORT_RESTRICTED_NAT

    public static final short PORT_RESTRICTED_NAT

  Port restricted cone NAT. Once we have sent a packet to a specific IP+Port, that IP+Port can send us packets on the port we just used.

  See Also:
    Constant Field Values

### SYMMETRIC_NAT

    public static final short SYMMETRIC_NAT

  Symmetric NAT. Uses a separate port number for each IP+port ! Not much hope for symmetric to symmetric...

  See Also:
    Constant Field Values

### SYMMETRIC_UDP_FIREWALL

    public static final short SYMMETRIC_UDP_FIREWALL

  Symmetric UDP firewall. We are not NATed, but the firewall behaves as if we were.

  See Also:
    Constant Field Values

### NO_UDP

    public static final short NO_UDP

  No UDP connectivity at all

  See Also:
    Constant Field Values
