Chapter 14 Zones

Intra-zone traffic is traffic between interfaces or VPN tunnels in the same zone. For example, in Figure 160 on page 245, traffic between VLAN 2 and the Ethernet is intra-zone traffic. In each zone, you can either allow or prohibit all intra-zone traffic. For example, in Figure 160 on page 245, you might allow intra-zone traffic in the LAN2 zone but prohibit it in the WAN zone. You can also set up firewall rules to control intra-zone traffic (for example, LAN2-to- LAN2), but many other types of zone-based security and policy settings do not affect intra- zone traffic.

Inter-zone traffic is traffic between interfaces or VPN tunnels in different zones. For example, in Figure 160 on page 245, 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 is traffic to or from any interface or VPN tunnel that is not assigned to a zone. For example, in Figure 160 on page 245, 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.
