Dashawn,
Charles Goldberg of Cisco Systems says,
"In 12.3(7)T Cisco introduced the notion of a Transparent Firewall.
With a Transparent Firewall there is no need to segment your network.
It works at Layer 2 in the traffic path but it gives you full Firewall Protection.
You can learn more about Transparent Firewall capabilities at:
http://www.cisco.com/en/US/products/sw/ ... ee193.html
BTW, in IOS, you can enable Transparent Firewall simultaneously with traditional Firewall if you choose."
