FULL_INTERNET

public static final short FULL_INTERNET

Full internet access!

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.

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.

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.

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...

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.

Constant Field Values

NO_UDP

public static final short NO_UDP

No UDP connectivity at all
