Intra-zone Traffic
• Intra-zone traffic is traffic between interfaces or VPN tunnels in the same zone. For example, in Figure
546 on page 794, traffic between VLAN 2 and the Ethernet is intra-zone traffic.
Inter-zone Traffic
Inter-zone traffic is traffic between interfaces or VPN tunnels in different zones. For example, in Figure 546
on page 794, traffic between VLAN 1 and the Internet is inter-zone traffic. This is the normal case when
zone-based security and policy settings apply.
Extra-zone Traffic
• Extra-zone traffic is traffic to or from any interface or VPN tunnel that is not assigned to a zone. For
example, in Figure 546 on page 794, traffic to or from computer C is extra-zone traffic.
• Some zone-based security and policy settings may apply to extra-zone traffic, especially if you can
set the zone attribute in them to Any or All. See the specific feature for more information.
