Configuring zones
In NAT/Route mode, you can use zones to group related interfaces and VLAN
subinterfaces. Grouping interfaces and VLAN subinterfaces into zones simplifies
policy creation. If you group interfaces an VLAN subinterfaces into a zone, you can
configure policies for connections to and from this zone, rather than to and from each
interface and VLAN subinterface.
You can add zones, rename and edit zones, and delete zones from the zone list.
A new zone does not appear in the policy grid until you add an interface to it (see
“Adding an interface to a zone” on page 143 ) and add a firewall address for it (see
“Adding addresses” on page 202 ).
This section describes:
• Adding zones
• Deleting zones
