When the NetRelay program is run, the user must specify several configuration parameters. These parameters may be specified in a configuration file, as demonstrated in Fig. 5, or they may be entered manually:
Internet port on the NetRelay computer to which the NetRelay program monitors for incoming connections.
Internet address and port number of the computer to which NetRelay will forward the connection.
Whether or not the incoming data is encrypted.
Whether or not the outgoing data should be encrypted.
The encryption password.
Whether all data passing through NetRelay should be displayed on the computer console window (for debugging purposes).
