STHome
You must specify the default route for the STHome via
the STHome local web pages. In this example, the IP address of
the default router would be 10.0.0.1, which is the IP address of
the Ethernet interface of the CPE router connected to the
STHome.
"
PCs or workstations:
For each PC you must add a route to their internal routing table.
This route must point to the STHome. For PCs equipped with
Microsoft Windows OSs, proceed as follows:
1. Select 'Start' from the Windows taskbar.
2. Select 'Programs'.
3. Select 'MSĆDOS' prompt.
4. In the DOS window, execute the command:
route add
In the example:
route add 10.0.0.138 172.16.0.1
To verify IP connectivity, you can ping the STHome. If it responds,
setting up PPTP tunnels is possible.
