The Zone Screen - ZyXEL Communications UAG4100 User Manual

Intra-zone Traffic
• Intra-zone traffic is traffic between interfaces in the same zone. For example, in
page 170, traffic between VLAN1 and the Ethernet is intra-zone traffic.
• You can also set up firewall rules 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
170, 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 102 on page
• 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.
