If you didn't install the documentation, you should.
You can read it on-line at http://docs.sun.com/db/doc/806-6347?q=sunscreen
and http://docs.sun.com/db/doc/806-6346?q=sunscreen
The first link is the Overview and the second one is the Administration
Guide.
Go to the chapter on Network Address Translation. You probably want to
do dynamic NAT. This stuff is in the Overview.
There is a GUI to configure NAT once you decide what you want to do. It
is explained in the Administration Guide.
Sorry, I don't have a simple cookbook answer for you; a lot depends on
what you want to do.

NO. Your internal addresses are not routable on the internet. It will
NEVER work that way.
