Networking in a Zone
--------------------

The following figure illustrates the network setup within a single zone.

|networksetupzone.png|

A firewall for management traffic operates in the NAT mode. The network
typically is assigned IP addresses in the 192.168.0.0/16 Class B private
address space. Each pod is assigned IP addresses in the 192.168.\*.0/24
Class C private address space.

Each zone has its own set of public IP addresses. Public IP addresses
from different zones do not overlap.
