1-Palo Alto Security Zone Overview

3. 1. Tap : Used in conjunction with SPAN/RSPAN to monitor traffic
2. Virtual Wire : Also known as Transparent Firewall.
3. Layer 2 : Used when switching between two or more networks
4. Layer 3 : Used when routing between two or more networks. Interfaces must be assigned an IP address
5. Tunnel : To set up a VPN tunnel
