The key to fox tunneling is the ORD syntax that is used to initiate tunneling from the Client station. Figure 2 illustrates the basic fox tunneling syntax (in the top of the graphic) and shows an example of the required syntax (station name instead of IP address) for target stations when the “Only Tunnel Known Stations” option is set to true.
In this graphic:
-
Proxy Server
This is the NiagaraAX-3.3 Supervisor station with an IP address that is available to the client station that you are currently using. The Proxy Server port number defaults to port 1911 (the standard default Fox port) unless otherwise specified.
-
Host Server
This is the station that you are trying to tunnel to. The Host Server address (like the Proxy Server address) may be followed by an optional port number. If not specified, the port number defaults to port 1911. You can complete the ORD by including the "space" and address of the desired view, if known.
-
Host, Session, Space
These are identified in the graphic above to indicate the standard segments of a typical ORD.
