Lon tunneling usage notes

In addition to these notes, be sure to see Best security practices for tunneling.

Lon tunneling is not supported for usage with remote network management tools, where the station is configured as “just a LON node” (see Notes when configuring as Lon node). In this case, the PC performing Lonworks network management should attach directly on the network.

When initiating a connection through the Lon tunnel, client-side usage is transparent except for the “virtual LONn” port used, and if “Interactive” is left enabled (typical) the resulting dialog right before the connection is attempted. Figure B.6 shows an example connection being initiated from a vendor’s Windows LON-based application. Tunneling client messages appear if the connection fails.

Speed of the tunnel connection may be slower that a direct (FTT-10) connection, due to the overhead of wrapping and unwrapping LonTalk messages in Niagara Fox and TCP/IP protocols. Tunneling is not recommended if using a “dialup modem” for connection to the target JACE station.
