following parameters:
Destination: 0.0.0.0/0
Source: Any

For each PC, you must add a route to its internal routing table.
This route must point to the STPro .
In the example of the figure above the route to be added to each
PC's routing table has the following parameters:
Destination: 10.0.0.138
Gateway: 172.16.0.1
You can verify connectivity from behind the IP router by applying a
