Hi Steve,

This sounds a bit like another problem we found recently.  Basically 
what happens is that the metric assigned to the tunnel route is of lower 
priority than some other route (like the default 0.0.0.0 route).

See if this thread on Windows 7's automatic route metrics is of any help 
to you:
