Seems like it's an binding order issue.
In Network places properties, click on
'Advance' menu and select Advaced Settings.
Move up or do wn the 3 NICs and set the order
properly, by your preferece of binding order.
From what you told, when your VSAT link is up you
may have to adjust the binding order again.
