L2 transparent mode: Zones, policies, & firewall authentication

Layer 2 transparent mode provides the ability to deploy the firewall without making changes to the existing routing infrastructure. The firewall is deployed as a Layer 2 switch with multiple VLAN segments and provides security services within VLAN segments. Secure wire is a special version of Layer 2 transparent mode that allows bump-in-wire deployment. Security zones, policies, and firewall authentication are supported with layer 2 transparent mode.
