One is a circuit-level "firewall" that implements only packet filters (the
Livingston), while the other (CheckPoint FireWall1, the product Sun OEM's)
is an application-level firewall, eveluating every packet and providing
logging and configuration at a high level of granularity.

I recommend you check out the firewalls mailing list. Send email to
majordomo@greatcircle.com with `subscribe firewalls <your email-address>'
on a single line in the body of the message. That list is significantly
more appropriate and will provide you more information. The differences
between a circuit-level gateway and an application-level firewall are
outlined in several FAQ's and books. Your remaining questions are also
frequently answered in that list and the books listed in the FAQ's.
