Method Details

expose

public static Set<PortMappingUtil.PortMapping> expose(InetSocketAddress address,
 PortMappingUtil.Protocol protocol)

Exposes address via PCP, NAT-PMP, or UPNP-IGD. This operation scans the local network for relevant routers. If no devices are discovered or no port forwardings can be created, this method will return an empty set.

Note: This is a blocking method, because it connects to other devices that may react slowly or not at all.

Parameters:

address - address to be exposed

protocol - protocol to be exposed

Returns:

List of port mappings.
