Thank You all who responded.

Boy, this a popular issue!
I had about 30 requests for a summary of what I received.

The summary is broken up into two parts.

The question was:
> We are looking to set up a firewall on a Sun Network
> which may have a connection to the Internet in the near
> future. I am in search of some white papers or written material
> which will help me decide the best way to accomplish this task.

 tcp-wrapper program
It allows you to wrapper any tcp request and
thus decide if a routing-match-table allows for the access either based on
hostname or IP number. The UDP side of this is a bit dodgy-ier but such
things do exist.

Look at the AnswerBook docs on ASET

Another possibility (that we use) is to use a Cisco router
as the 'firewall' with filtering per port and per protocol.
With our setup, only certain hosts on the internet can telnet in.
But anyone on the inside can freely telnet/ftp out.
