Depends on how nit-picky you want to get with the definition of a firewall.
FIREWALL; A system, combination of systems, or security policy that enforces
a boundary between resources, hosts, or networks.
BASTION HOST; A hardened system expected to potentially become attacked by
intruders. Usually placed between the internet and an internal LAN.
These definitions may not be widely accepted, but depending on how you
define what a firewall is, what you describe below kinda fits.
Never heard of TopSecret, but I'd consider it a firewall product from what
you describe.
