iSTAR Ultra Installation and Configuration Guide 3–3
Local Address Management
Although it is not required, System Managers who want to maintain local address
management can configure iSTAR Ultra with locked IP addresses. Locked IP addresses retain
the iSTAR Ultra address that is specified locally or by a local Dynamic Host Configuration
Protocol (DHCP) server. When IP addresses are locked, iSTAR Ultra communicates across
gateways using only the IP address that you configure: translated addresses are not accepted.
Before you lock an IP address, ensure that it is reliable (not subject to translation) and can be
reached from the local network.
Example:
The example displayed in Figure 3-2 on page 3-4 shows a locked iSTAR Ultra configuration.
To configure this cluster, the System Manager is in the branch office:
Use PING to check communication to the exposed (translated) address from the Corporate
Office.
Use the ICU to configure the master controller and lock the exposed C•CURE address.
Use the ICU to configure the member controllers and lock the local subnet addresses.
