Collection<InetSocketAddress> de.fu_berlin.inf.dpp.net.stun.IStunService.discover	(	String	stunAddress,
		int	stunPort,
		int	timeout
	)

Starts a WAN (public / external) IP discovery of this system using STUN protocol RFC 5389 via UDP.

Parameters:

stunAddress	address of the STUN server
stunPort	port of the STUN server, if 0 the default STUN port is used
timeout	timeout in milliseconds before the discovery is aborted

Returns:

the currently discovered public IP addresses and the port associated with this IP.

this method blocks until the discovery has finished or the timeout is exceeded

Implemented in de.fu_berlin.inf.dpp.net.stun.internal.StunServiceImpl.

Collection<InetSocketAddress> de.fu_berlin.inf.dpp.net.stun.IStunService.getPublicIpAddresses

(

)

Returns the currently discovered public IP addresses. The collection will be empty if no discovery has performed yet, is still running or failed. The collection may also be incomplete if the discovery process has not finished for all network interfaces at the time this method is called.

Returns:

the currently discovered public IP addresses and the port associated with this IP.

Implemented in de.fu_berlin.inf.dpp.net.stun.internal.StunServiceImpl.

boolean de.fu_berlin.inf.dpp.net.stun.IStunService.isDirectConnectionAvailable

(

)

Returns whether one of the available network interfaces is connected directly to the Internet.
