All Implemented Interfaces:

java.lang.Cloneable, Daemon, HasTransform, java.util.Observer, Owned

public class Tunnell

extends Gate

implements Daemon, java.util.Observer

This Gate connects to the remote host on startup. When connected, it updates it's attributes and listens for incoming connections. When anything comes from the server, tries to start new local Session. If sucessfull, opens another connection to the server. This Connection/Session pair is used when server cannot listen for incoming connections, i.e. behind firewall.
