If the client's firewall allows outgoing connections to the Internet,  
then the client will connect directly to the manager's GCB broker,  
which will connect to the manager and relay data between the two  
connections.

Because the client is connecting directly to the manager's GCB  
broker, the manager's GCB broker will see the client's real IP address.
