The STPro allows local tunneling from behind an IP router:

IP Network 10

IP Network 172.16

10.0.0.138 10.0.0.1

172.16.0.1

172.16.0.3

172.16.0.2

Ethernet LAN

IP Router Local PPTP tunnels

This requires settings in both STPro and PCs.

You must add a default route for the STPro via the 'Routing' page

(See section 14.5 for more information).

In the example of the figure above the route to be added has the

following parameters:

 Destination: 0.0.0.0/0

 Source: Any

 Gateway: 10.0.0.1

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

ping to the STPro.
