Explanation

Tap: Used for passive monitoring of traffic. The firewall receives a copy of the traffic for inspection but does not interfere with the traffic flow. Layer 3: Interfaces operate at Layer 3 (IP Layer) and are assigned IP addresses. The firewall can route traffic between networks using Layer 3 interfaces. Virtual Wire: Also known as "transparent mode." The firewall connects two network segments without any Layer 2 or Layer 3 changes. It's typically used for inline deployments without reconfiguring IP addressing.
