Chapter 34 Zones Intra-zone Traffic • Intra-zone traffic is traffic between interfaces in the same zone. For example, in Figure 267 on page 395, traffic between VLAN1 and the Ethernet is intra-zone traffic. • You can also set up security policies to control intra-zone traffic (for example, LAN1-to-LAN1), but many other types of zone-based security and policy settings do not affect intra-zone traffic. Inter-zone Traffic Inter-zone traffic is traffic between interfaces in different zones. For example, in Figure 267 on page 395, traffic between VLAN1 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 that is not assigned to a zone. For example, in Figure 267 on page 395, 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. 34.2 The Zone Screen The Zone screen provides a summary of all zones. In addition, this screen allows you to add, edit, and remove zones.
