Examples of NATSituation

de.fhkn.in.uce.plugininterface.NATSituation
A {@link NATSituation} represents a constellation of two NAT devices, the NATdevice on the client-side and the NAT device on the server-side. Multilevel NAT devices are also represented by a NAT situation because for a public reachable peer multilevel NATs behave like a single NAT. @author Alexander Diener (aldiener@htwg-konstanz.de)
