9. In the Internal Network setup page, click the Select Network Adapter button.
10. In the Select Network Adapter dialog box, remove the checkmark from the Add the
following private ranges… checkbox. Leave the checkmark in the Add address ranges
based on the Windows Routing Table checkbox. Put a checkmark in the checkbox next

checkmark from the add private address ranges checkbox is that you may wish to use
these private address ranges for perimeter networks. Click OK.
